Buccaneers sign Donovan Raiola

TAMPA, Fla. -- The Tampa Bay Buccaneers have re-signed center Donovan Raiola to add depth to an injury-riddled offensive line.

Raiola initially signed with the Bucs in June and was released following training camp. He fills a roster spot that opened Monday when the club said starting center Jeff Faine will be lost for the season to a triceps injury.

Raiola entered the NFL as an undrafted free agent and spent time last season with Arizona Cardinals and Chicago Bears.
