NEW YORK -- Four-time major champion Maria Sharapova pulled out of the U.S. Open on Wednesday because of a right shoulder injury. "Maria Sharapova is one of the great warriors of the tennis world," U.S. Tennis Association Executive Director and COO Gordon Smith said. "If she withdrew, theres a serious issue." Sharapova, the 2006 champion at Flushing Meadows, has played only one match on tour since her second-round loss at Wimbledon in June. "I just wanted to let you know that withdrawing from the U.S. Open has been a really tough decision to make. I have done everything I could since Wimbledon to get myself ready but it just wasnt enough time," read a message posted on Sharapovas Facebook page Wednesday night. "I have done many tests, received several opinions and it all comes down to taking the proper amount of time to heal my shoulder injury properly." The posting added that Sharapova plans "on taking the next few weeks off, receiving proper treatment and rehabilitation." She originally was seeded third at the U.S. Open. The USTA said 2012 Wimbledon runner-up Agnieszka Radwanksa would shift from No. 4 to No. 3, and all other seeded players below her would move up a spot, too. Anastasia Pavlyuchenkova will become the tournaments new 32nd seed. The draw for the years last Grand Slam tournament is Thursday. Play begins Monday. Sharapovas surprising exit caps a tumultuous couple of weeks for the former No. 1 player. The Russian was sidelined by a hip injury after Wimbledon. Then she hired Jimmy Connors as her coach, an arrangement that lasted all of one match, a loss, at the Mason, Ohio, hard-court tournament. Sharapova last missed the U.S. Open in 2008, when she was off the tour for about 10 months because of surgery on her right shoulder. She won her first major title since that operation at last years French Open, completing a career Grand Slam. Earlier Wednesday, former top-10 player Mardy Fish of the United States withdrew from the U.S. Open, citing personal reasons.

The Bears officially announced Rhoades hire while Odom was standing on the stage Wednesday discussing the programs future.I found out last night and didnt have any clue before then, Odom said. I respect Mack calling me and having the conversation.Odom was promoted in December after longtime coach Gary Pinkel retired and announced he was fighting cancer. Rhoades promoted Odom from defensive coordinator and gave him a five-year contract worth $2.35 million annually.The coach said he wasnt worried about job security -- only the results of the program moving forward.I know Ive got a group of guys coming back that are anxious and excited about getting the 2016 season started, Odom said.But first, Odom had to deal with the news of Rhoades departure.Rhoades was hired by Missouri 16 months ago, but much has changed since then.

Both the president and school chancellor, R. Bowen Loftin, resigned.Missouri linebacker Michael Scherer, who was second on the team with 93 tackles last season, said the constant distractions arent ideal, but they would cope with Rhoades surprising departure just like everything else.What are you going to do about it?, Scherer said. I cant do anything to change it. Nobody here can do anything to change whats happened. You just have to move forward and keep going on like nothings wrong. Like nothings changed.Thats just kind of how we deal with things.On the field, the Tigers have 13 starters returning from a team that finished with a 5-7 record, including a 1-7 mark in the SEC. Missouri especially struggled on offense, especially during the last half of the season, and averaged a league-low 13.6 points per game.Sophomore Drew Lock returns after throwing for 1,332 yards, four touchdowns and eight interceptions. He completed just 49 percent of his passes.While the offense is rebuilt, the Tigers might have to rely on their defense. Missouri has eight starters returning, including Scherer and Charles Harris, who led the SEC with 18 1/2 tackles for a loss last season.---Follow David Brandt on Twitter: www.twitter.com/davidbrandtAP---AP College Football website: www.collegefootball.ap.org .
