The Bucs lost more than at game at Atlanta Sunday. It also claimed two of their best offensive linemen.
Center Ali Marpet and tackle Demar Dotson were placed on injured reserve Wednesday. Both suffered knee injuries in Sunday's 34-20 loss to the Falcons, although both were tough enough to finish the game.
Marpet, 24, the third year pro from Hobart College, made the move from guard to center this season and had consistently graded out as the Bucs' top offensive lineman this season. Dotson, 32, is in his ninth season and was having one of his best years but had been playing through a hamstring injury that limited his ability to practice.
The Bucs currently have only seven offensive linemen on the 53-man roster. Marpet likely will be replaced by center Joe Hawley, who was the Bucs primary starter at that position for 2015-16. Caleb Benenoch would be a candidate to replace Dotson at right tackle.
Guard/center Evan Smith has been in concussion protocol. If he is able to play Sunday at Green Bay, the Bucs could move him to left guard and play Kevin Pamphile at right tackle.
The Bucs also promoted tight end Alan Cross, defensive end Patrick O'Connor and wide receiver Bobo Wilson from the practice squad to the active roster and signed cornerback Deji Olatoye (pronounced Day-zhee OH-la-toy-aye) to the active roster.
