The Tampa Bay Buccaneers have signed defensive end Jeff Charleston to fill a roster spot that opened when Adrian Clayborn was placed on injured reserve.
Clayborn is out for the season after hurting his right knee during last Sunday's 16-10 loss to the Dallas Cowboys. Charleston practiced with the team for the first time on Wednesday.
Charleston is a sixth-year pro who spent four seasons with the New Orleans Saints after playing with the Indianapolis Colts as a rookie in 2007. He has appeared in 65 games with four starts and has eight career sacks.
Coach Greg Schiano said Wednesday that third-year pro Daniel Te'o-Nesheim will move into Clayborn's starting right end position.
