SAN FRANCISCO >> Cornerback Eric Wright has failed his physical with the San Francisco 49ers and will return to the Tampa Bay Buccaneers.

San Francisco coach Jim Harbaugh declined to say specifically what portion of the physical Wright failed.

Wright was traded to the 49ers on Friday in exchange for a conditional draft pick in 2014, one week after he was arrested in Los Angeles on an unspecified misdemeanor charge. Wright was also suspended for four games last season by the NFL for violating the performance-enhancing drug policy in his first season with the Bucs.

His rights now revert back to Tampa Bay. A second-round pick of the Cleveland Browns in 2007, Wright signed a five-year, $35.3 million contract with the Bucs prior to the 2012 season.
