Reigning champion Rafael Nadal pulled out of the U.S. Open because of an injury for the second time in three years Monday, leaving Novak Djokovic and Roger Federer as the men to beat at the year's last Grand Slam tournament.

Nadal announced his withdrawal, blamed on a bad right wrist, one week before play begins at Flushing Meadows.

"I am sure you understand that it is a very tough moment for me since it is a tournament I love and where I have great memories from fans, the night matches, so many things," a posting on Nadal's Facebook page read.

The second-ranked Nadal plays left-handed, but he uses a two-handed backhand.

The 14-time major champion was hurt July 29 while practicing on his home island of Mallorca ahead of the North American hard-court circuit.

Nadal is 44-8 with four titles in 2014, including his record ninth French Open trophy in June. He has not competed since losing in the fourth round of Wimbledon on July 1.

Two-time Big Ten offensive player of the year Braxton Miller of Ohio State, considered among the top contenders for the Heisman Trophy, reportedly reinjured his throwing shoulder in practice. Ohio State officials declined to confirm that the quarterback was hurt again or speak to the severity of the injury, first reported by The Columbus Dispatch.

Miller, a senior, had missed all of spring practice after what was termed "minor, outpatient surgery" on his right shoulder.

Hennepin County prosecutor Mike Freeman made the announcement, saying there "is not proof beyond a reasonable doubt" that Cunningham committed the crime. Cunningham was charged in April for allegedly choking his then girlfriend.

Cunningham maintained his innocence throughout the process. He spent the last two seasons with the Minnesota Timberwolves. He became a free agent this summer, but several teams told him they would wait for the legal process to play out before considering signing him.
