TAMPA, Fla. -- Buccaneers left tackle Donovan Smith will miss the next two to four weeks with a sprained right knee, a source confirmed to ESPN's Dan Graziano.
NFL Network earlier reported the extent of and timetable for Smith's injury. Team sources tell ESPN that they are "optimistic" that it won't be a long-term injury.
Smith was injured at practice Tuesday morning when he got rolled up on during a team period.
"One of the defensive guys threw themselves into him, or got thrown into him," said right tackle Demar Dotson.
