RIO DE JANEIRO -- Novak Djokovic will face 2009 US Open champion Juan Martin del Potro in the first round of the Olympics in a rematch of the 2012 bronze medal match.Del Potros ranking has fallen to 145th after he endured three operations on his left wrist. But at his first Grand Slam in 2 1/2 years, he upset fourth-seeded Stan Wawrinka at Wimbledon last month. The Argentine beat Djokovic for bronze in London four years ago.The top-ranked Djokovic, a 12-time major champion, is seeking his first Olympic title. A potential semifinal opponent in Rio de Janeiro is third-seeded Rafael Nadal, who hasnt played since withdrawing from the French Open because of a left wrist injury.Reigning gold medalist Andy Murray could face fourth-seeded Kei Nishikori in the semifinals. The Wimbledon champion will meet 35th-ranked Viktor Troicki in the first round in the 64-player draw, which was announced Thursday.Hes one of the better players thats not seeded, Murray said. He likes the hard court. Good competitor, good mover. Definitely a tough opening match.In the womens draw, top-ranked Serena Williams, the reigning gold medalist, could face older sister Venus in the semifinals. Also on her half of the draw is Spains Garbine Muguruza, who beat the 22-time major champion in this years French Open final. And a potential quarterfinal opponent is Italys Roberta Vinci, who stunned Williams in last years U.S. Open semifinals to end the Americans Grand Slam bid.The Williams sisters, coming off a Wimbledon title, are seeded first in doubles as they seek their fourth gold medal together.The tournament starts Saturday, though Murray, who will be Britains flag bearer at Fridays opening ceremony, doesnt play until Sunday. He is also seeded second in doubles with older brother Jamie, who won this years Australian Open title with regular partner Bruno Soares of Brazil. Andy Murray said he considered his Olympic singles and doubles competitions to be of equal importance.The Murray brothers face two other Brazilians, Thomaz Bellucci and Andre Sa, in the first round.Im sure the crowd will be pretty lively, Jamie Murray said.Its going to be a tough team, he added, and obviously inspired to play in their home Olympics. Expect them to perform well.Wawrinka and Roger Federer were expected to contend for another doubles gold medal for Switzerland, but both pulled out of the Olympics because of injuries, leaving the Rio Games without two of the top four men in the rankings. Overall, half of the top 20 wont be in Brazil for various reasons, though the draw still has the star power of Djokovic, Murray and Nadal.Murray noted that if not for injuries to Federer and Wawrinka, every mens Grand Slam champion of the past decade-plus would be in Rio.It is unfortunate. The Olympics in London was very strong, Murray said. Because of a few injuries and some of the potential health problems, its made it a little bit weaker this time around.Everyone views things differently. For me, the Olympics is the biggest sporting event by far, and Im proud to be here representing my country. Youth Giants Jerseys . Sgt.

Coach Mike Munchak says Fokou stretched ligaments in his left knee Oct. 13 against Seattle, which could keep out up to five weeks even though the linebacker didnt need surgery. Kyle Lauletta Jersey .

Michael Strahan Jersey . -- James Young couldnt wait to apply those tweaks to his jump shot, and the first one he made against UT Arlington told him it could be a good night. MORGANTOWN, W.Va. -- No. 25 West Virginia left the championship game of the NIT Season Tipoff with a loss and multiple teaching points.We didnt guard, coach Bob Huggins said after Fridays 81-77 loss to Temple in Brooklyn. We didnt guard the way were capable of guarding. Our help defense was atrocious. We fouled too much. We didnt make free throws. We missed open shots. We missed 17 layups -- 17 point-blank at the rim.The Mountaineers (4-1) trailed 45-25 at the half, reclaimed the lead with eight minutes left and then failed to finish a game in which they were heavily favored.On Monday night, when Huggins team returns to action against Manhattan (2-3), hes hoping for more consistent defense -- not just the suffocating spurt WVU showed during the second half against Temple. Hes also bothered by 60 percent foul shooting and the Mountaineers penchant for committing too many turnovers themselves. They forced 19 by Temple only to give back 16.Thats a formula for disaster, Huggins said.If there was a positive from the defeat, sophomore forward Esa Ahmad scored a career-high 19 points, becoming the offensiive force many fans envisioned.ddddddddddddNathan Adrian (13.2 points, 7.8 rebounds) and Ahmad (12 points, 5.4 rebounds) give West Virginia versatile forwards. Jevon Carter (9.6 points, 4 assists, 3.6 steals) and Tarik Phillip (9.6 points, 3.6 rebounds) lead a rotation of five guards that figures only to grow stronger with Daxter Miles (5.5 points) regaining his conditioning after a three-game illness absence.The Jaspers, picked fourth in the Metro Atlantic Athletic Conference, also have lost to Temple, 88-67, on Nov 20. They edged Detroit 84-81 in double-overtime on Saturday behind 32 points by guard Zavier Turner. The 5-foot-9 Ball State transfer averages 19.4 points and three assists per game.Forward Zane Waterman (11.4 points, 7.4 rebounds) and freshman guard Aaron Walker (10.2 points, 4.0 rebounds) could be key if Manhattan is to stop West Virginias trend of blowing out mid-majors in Morgantown. The Mountaineers have won three home games by an average of 40 points.
