Firkser (knee) didn't practice Wednesday, Turron Davenport of ESPN.com reports.
Firkser was a limited participant last Wednesday and Thursday before sitting out entirely Friday. He then missed Tennessee's win over Seattle, with his usual snaps at tight end being split between Geoff Swaim and MyCole Pruitt. The absence Wednesday suggests Firsker could miss another game this Sunday against the Colts.
