Marcus Mariota insisted his left knee isn’t a concern and that he’ll be ready to go Saturday when No. 6 Oregon hosts Utah. There are lingering questions about how much the mysterious injury contributed to the Ducks’ loss at Stanford Thursday. Oregon doesn’t discuss injuries, and the sophomore quarterback hasn’t been specific. Mariota’s outstanding season has him in the Heisman conversation . . . Florida quarterback Tyler Murphy probably will be a game-time decision against No. 11 South Carolina Saturday, offensive coordinator Brent Pease said. Murphy sprained his right shoulder against LSU last month. If Murphy can’t play, redshirt freshman Skyler Mornhinweg, son of New York Jets offensive coordinator Marty Mornhinweg, would make his first start . . . Florida State announced that backup quarterback Jacob Coker will miss the rest of the season after having knee surgery. The sophomore tore cartilage during Saturday’s win against Wake Forest. Redshirt freshman Sean Maguire will now back up Heisman candidate Jameis Winston . . . Connecticut interim coach T.J. Weist announced that redshirt freshman Casey Cochran will start Saturday for winless UConn at SMU. Cochran takes over for freshman Tim Boyle, who started the last four games after replacing junior Chandler Whitmer . . . Richland County Sheriff Leon Lott said that former South Carolina running back Kenny Miles shot himself in the arm, but told investigators it happened during a robbery, and the ex-player will be charged with filing a false police report. Miles issued a statement through his lawyer saying he made a mistake on Nov. 4 and that he was not involved in anything criminal. Miles spent most of his career backing up Marcus Lattimore, running for 1,341 yards. Miles graduated with a degree in criminal justice.
Stamkos undergoes surgery in Boston
Tampa Bay star Steven Stamkos had what the team called ‘‘successful surgery’’ at Massachusetts General Hospital to stabilize a fracture in his right tibia. The high-scoring center is expected to return to Tampa on Thursday to begin rehabilitation. A timetable has not yet been set for his return. Stamkos was injured on Monday with 7:11 remaining in the second period against the Bruins. He was taken off the ice on a stretcher after crashing into the post . . . The Blackhawks agreed to terms with forward Andrew Shaw on a two-year extension through the 2015-16 season. The 22-year-old had nine goals and six assists in 48 games last year, his first full season in the NHL. He added five goals and four assists as the Blackhawks won the Stanley Cup, and is currently sixth on the team with 11 points through 18 games . . . After an hour-long spin on the Madison Square Garden ice, Rangers forward Rick Nash is ready to practice with his teammates and could rejoin the lineup soon. Nash skated for the fourth straight day and remained symptom-free from a concussion sustained Oct. 8 at San Jose. Including Tuesday night against New Jersey, Nash has missed 15 games since he was hit in the head by Sharks defenseman Brad Stuart and sustained his second concussion in eight months . . . Dallas placed forward Ray Whitney on injured reserve with a lower-body injury. The 41-year-old has played in all 17 games and is third on the team with seven assists. Whitney was injured in a 5-2 loss to the Blackhawks on Saturday . . . General managers discussed a host of topics at their annual post-Hall of Fame meeting in Toronto. No formal rule changes came about, though the purpose of the get-together is more to set up March’s meeting. Detroit GM Ken Holland’s idea to extend overtime to 10 minutes got discussion. He wants four-on-four for five minutes, then three-on-three for another five. Fighting was discussed in general terms, and a rule was brought up to punish goaltenders who crossed the center red line to fight.
NASCAR’s Bayne has MS, will still ride
NASCAR driver Trevor Bayne said that he has multiple sclerosis and he does not expect it to impact his racing career. Bayne, who in 2011 became the youngest winner in Daytona 500 history, will still compete as scheduled at Homestead-Miami Speedway this weekend in the Nationwide and Sprint Cup Series finales. Bayne’s younger sister, Sarah, also has multiple sclerosis. The 22-year-old Bayne was sidelined for five races in 2011 for an illness that led to hospitalization. Doctors ultimately called it an ‘‘inflammatory condition,’’ and it was never made clear if it was related to an insect bite he’d suffered weeks earlier . . . The Bulls said Derrick Rose is day to day with a sore right hamstring. Rose winced after he drove down the lane for a twisting layup with 3:39 left during Chicago’s 96-81 victory over Cleveland Monday night. Rose called it a minor sprain, and the 2011 NBA MVP thought he would be able to play Friday night at Toronto . . . Cycling is weeks away from setting up an independent commission to investigate the sport’s drug-stained past, World Anti-Doping Agency President John Fahey said. Fahey will meet Wednesday with Brian Cookson, the new president of cycling’s governing body, to discuss the fallout from the Lance Armstrong scandal. The outgoing WADA chief said it would take ‘‘something close to a miracle’’ for Armstrong’s life ban to be reduced in return for cooperating with the investigation.
