TAMPA — CB Elbert Mack's appeal of a one-game league suspension was denied Friday, leaving the Bucs without the reserve for Sunday's game at Chicago.
The rookie out of Troy was suspended without pay for his helmet-to-helmet hit Sunday on Falcons QB Matt Ryan during a fumble return by the Bucs.
Mack appealed the suspension under provisions in the collective bargaining agreement. To replace him, the Bucs signed Marcus Hamilton from the practice squad.
"We've got to get another man up and ready to play," coach Jon Gruden said. "If you remember, Marcus had a good training camp, and he'll play if needed."
The Bucs use at least three cornerbacks on nearly half their defensive snaps, making the need for a fourth crucial. Hamilton will back up Ronde Barber, Phillip Buchanon and Aqib Talib.
It is the second time Mack has been cited for what the league calls a flagrant violation of player safety rules. He was fined $5,000 for his first infraction, an unnecessary roughness penalty on Texans QB Alex Brink in the Aug. 28 preseason finale. His second infraction will cost him a game check, $18,437.
INJURY REPORT: The team's final injury report of the week confirmed what was expected: WR Joey Galloway won't play Sunday. Galloway suffered what the team called a foot sprain against Atlanta last week.
Elsewhere, Talib (hamstring), LB Derrick Brooks (hamstring) and DE Gaines Adams (abdomen) are questionable, though it's expected each will play.
For the Bears, WR Devin Hester (ribs) will be a game-time decision. He was unable to practice Friday.
