Black were placed on injured reserve Tuesday.

The Buccaneers promptly filled one of the two new openings on the practice squad by re-signing linebacker J.D. Folsom, who had a brief stint on that same unit earlier in the season.

With Johnson's promotion, there are now six members of that original practice squad on the Bucs' active roster. He joins previous call-ups safety Vince Anderson, tackle Will Barker, wide receiver Dezmon Briscoe, guard Derek Hardman and tight end Ryan Purvis. Only punter Brent Bowden and linebacker Lee Robinson are no longer with the team; Robinson is currently a member of the Denver Broncos' active roster.

In all, there are now 11 players among the team's 53 actives who previously spent time on the team's practice squad this year: the aforementioned seven plusguard Brandon Carter, cornerback D.J. Johnson, fullback Erik Lorig and defensive tackle Frank Okam.

The additions of Johnson and McKenzie will help repair the depth issues caused in the front seven with the most recent pair of season-ending mishaps. The injuries to McCoy and Black against the Washington Redskins on Sunday forced the Buccaneers to put two starters on injured reserve for the third straight week. The previous four were safety Cody Grimm, cornerback Aqib Talib, guard Davin Joseph and center Jeff Faine.
