Incredibly enough, with two days left in the mens tennis season, we still dont know who will wind up with the No. 1 ranking.No. 1 Andy Murray and No. 2 Novak Djokovic could meet in Sundays championship for Barclays ATP World Tour Finals -- marking the first time in tournament history that two finalists would determine the No. 1 ranking.In Saturdays semifinals at Londons O2 Arena, Murray faces No. 4 Milos Raonic, and later Djokovic meets No. 5 Kei Nishikori.After beating Stan Wawrinka 6-4, 6-2 Friday, Murray was asked if it mattered whether the pivotal match with Djokovic came sooner or later.I mean, theres a good chance that if I want to win the tournament, I would have to win against him, he told the media. That would either be in the semis or the final. I dont think that makes a whole lot of difference.Im certainly not taking anything for granted. I know it will be hard. But, yeah, I feel like my games in a good place.Heres a breakdown of the two semifinal matches:Andy Murray versus Milos Raonic, 9 a.m. ET on ESPN3Round-robin records: Murray 3-0; Raonic 2-1Career head-to-head: Murray leads 8-3 (with three walkovers)W2W4: Turns out, life atop the tennis universe hasnt been a burden after all. Murray won all three of his round-robin matches this week and five of six sets. And while he still seemed frazzled and frustrated at times (notably against Nishikori in his second match), he has largely contained his outbursts. Its that kind of cerebral composure that has historically been his biggest enemy. And when you factor in all that is on the line in London -- winning a first ATP Finals title, securing it in front of his home fans and holding on to the top ranking -- Murray deserves credit for the manner in which he swept his way to the final four -- the first time since 2008 hes reached the semifinals unbeaten.Truth be told, its never been better. Murray has won 22 consecutive matches, equaling his career best -- which came earlier this year. He was masterful against Wawrinka, but his opponent Saturday is also playing some of the finest tennis of his career. Raonic has crafted a stellar 52-15 record, and the faster courts and indoor conditions of the O2 Arena make his serve more lethal than it already is. Hes slugged a tournament high 40 aces through three matches.But more telling beyond this tangible stuff is the manner in which Raonic, who could end the season ranked a career-high No. 3, talks about playing big in the seminal moments, as he did in a must-win match against Dominic Thiem on Thursday: Theres a lot definitely to be proud of, playing under that kind of pressure, cause I really wanted to get out of the group stages and I wanted to give myself a chance in the semifinals, he said to the media after a straight-sets win that propelled him into the semifinals.Murray is keenly aware Raonic took Djokovic to a pair of tiebreakers and is comfortable in this venue. Yeah, you dont normally get loads of opportunities against the big servers, Murray said. Then it comes down to when you do get those chances, whether you take them or not. And this year when Ive played him, Ive created a few opportunities in the matches. When theyve come, Ive been pretty clinical.Ill need to be the same tomorrow if I want to win.Prediction: Murray in two.Novak Djokovic versus Kei Nishikori, 3 p.m. ET on ESPN3Round-robin records: Djokovic 3-0; Nishikori 1-2Career head-to-head: Djokovic leads 10-2W2W4: Finally, Djokovic will play someone who has a career win against him. He was 23-0 versus his round-robin group heading into the ATP World Tour Finals and swept his three matches this week. Nishikori has beaten Djokovic twice, most notably in the 2014 US Open semifinals. Nishikori has played strong tennis since the summer hard-court season began. In August, he took down Rafael Nadal to win bronze at the Rio Olympics, and then a few weeks later made the US Open semifinals. Nishikori came into the year-end championships just a couple of weeks removed from a finals appearance at the Swiss Indoors. In his opener this week, he manhandled Wawrinka and narrowly lost to Murray in a three-setter Wednesday.But this matchup will likely be determined by Djokovics state of mind. For a player who preaches harmony and relaxation, he has been on edge all week, snapping at chair umpires and smashing rackets. Nearly unbeatable through the French Open, Djokovic, who had a commanding lead in the rankings during the summer, has battled himself as much as his opponents in recent months. He squirrely existence has raised questions as to what (and why) his game has fallen. Nonetheless, after dropping the opening set to Thiem last Sunday, Djokovic sailed the rest of the way in London, including a one-hour shellacking of alternate David Goffin, who filled in for injured Gael Monfils on Thursday.Remember, not only is the championship on the line, but so is the No. 1 ranking, an honor -- even if he has not admitted it -- Djokovic believes he deserves. For the first time since his tenure atop tennis began 223 weeks ago, few have questioned whether he is the best player in the game. But the feeling now is that as he closes in on 30 years old, his game has dropped, while the landscape is slowly shifting. Still, with two full days left in the regular season, Djokovic has corralled a final boost of intensity. I can say from my perspective that I always try to really take the last drop of energy, whatever is left in my body, to perform as well as I can and finish off the season in the best possible way, he told the media after beating Goffin.Prediction: Djokovic in three Brad Maynard Jersey .

Thats about all he can do right now, so hes trying not to think about when he might be able to play again for the Los Angeles Lakers. Custom David Montgomery Jersey . JOHNS, N. Tony Romo taking snaps. Joe Flacco hurling passes. Jordy Nelson and Keenan Allen catching them.Terrell Suggs and Cam Wake harassing opposing quarterbacks. Ryan Clady trying to prevent such things.Jamaal Charles running wild.It sure would be nice to see these stars on the field and not on injured reserve, where they wound up in 2015.As NFL teams head to training camp, nearly all of them have key players they desperately need to return to health. Heres a look at those most in need.BALTIMORE -- No team had its season ruined more by injuries than the Ravens. Along with Flacco and Suggs, they lost half-dozen regulars, including playmakers Steve Smith Sr. and Justin Forsett.Flacco, the 2013 Super Bowl MVP, played in 122 straight games, fifth-longest string for a quarterback in NFL history, before tearing his left ACL and MCL in November. He believes he is on pace to start the preseason.I wanted to be the guy who played 15, 16, 17 years and didnt miss a snap, Flacco said. I had to come to grips with it pretty quickly because it was my reality. That was the toughest part, not being able to be on the field with the guys for the last six games.Suggs wasnt on the field for almost the entire 2015 schedule. The six-time Pro Bowl linebacker tore his Achilles tendon in the opener at Denver.He has not been available to talk about his rehab, but coach John Harbaugh is optimistic Suggs will be ready for training camp.DALLAS -- Around Big D, folks fully believe Romos return to health will ensure the Cowboys return to the postseason. Hell likely need a similar recovery by receiver Dez Bryant -- and a vastly improved defense that includes the return of cornerback Orlando Scandrick -- for that to happen.But having Romo on hand instead of Brandon Weeden or Matt Cassel or Kellen Moore, well, need we say more?MIAMI -- After spending all those millions on DT Ndamukong Suh, Miamis defense ranked 25th overall, 28th against the run. It had 31 sacks; opponents had 45.And now, sacks leader Olivier Vernon is a Giant.That means Wake will need to, uh, wake up a unit that surrendered 44 touchdowns.dddddddddddd Hes coming off a torn left Achilles tendon that cost him nine games.Wake has averaged 10 sacks for his seven seasons and is a four-time Pro Bowler.Its another obstacle to overcome, he said. Ive been doing it my whole career. I wouldnt expect this to be any different.NEW YORK JETS -- Clady has never played a snap for the Jets, who gambled and traded for him after mainstay DBrickashaw Ferguson retired. They hope he can fill a massive hole at left tackle, something Clady has done exceptionally well for most of the seven pro seasons hes gotten onto the field.Last year wasnt one of them; Clady missed Denvers championship run with a torn left ACL sustained in May 2015. Two years before that, he managed to get into only two games before a Lisfranc foot injury sidelined him.He really is New Yorks only viable option at the important LT position.Im just going to answer them by getting on the field and playing, he said of those who question his ability to return to top form. I think I can do that.GREEN BAY -- It could be argued that no players recovery is more critical to his teams title chances than Packers wideout Nelson from a torn right ACL. Even with good health for Romo, Flacco, Suggs, Wake and Clady, their teams are dealing with many other issues.Not so much in Green Bay, which has the elements to be a solid contender in the NFC. If, that is, Nelson is back to supply Aaron Rodgers with a reliable threat all over the field in the passing game. Which, incidentally, will help boost the run game.I just need to make sure Im ready to go come the start of training camp and the regular season, Nelson said. Thats where Im trying to get to. I know where I need to be mentally and physically.If he gets there, Cheeseheads everywhere can breathe easier.---AP NFL website: www.pro32.ap.org and www.twitter.com/AP-NFL ' ' '
