Bucs' Clayborn lost for season

The Tampa Bay Buccaneers placed defensive end Adrian Clayborn on injured reserve Monday, one day after he hurt his knee during the team's loss at Dallas.

Clayborn, Tampa Bay's first-round selection in the 2011 NFL Draft, sustained the injury during the fourth quarter of Sunday's 16-10 loss to the Cowboys. According to the Tampa Bay Times, the 24-year-old tore a ligament in his knee and would need season-ending surgery.

The 20th overall choice of the 2011 draft, Clayborn has started all 19 games for the Buccaneers since entering the league and topped Tampa Bay with 7 1/2 sacks while recording 54 tackles during a solid rookie season. The Iowa product's sack total was the second-highest by a rookie in team history.
