The Buccaneers promoted linebacker Josh Keyes from their practice squad Saturday and waived tight end Alan Cross to make room for Keyes on the active roster.
Teams have until 4 p.m. EST the day before games to make such moves, which are fairly common as the season moves along.
Keyes played in seven games for the Bucs last season. He was waived during final roster cuts, then added back to the practice squad.
The Bucs also signed tight end/fullback Danny Vitale to their practice squad. The Bucs drafted Vitale in the sixth round last spring, and he was briefly signed by the Bills after being released.
