Burkhead (concussion) didn't practice Wednesday, Scott Petrak of the Elyria Chronicle-Telegram reports.
Burkhead was forced out of Sunday's loss at Miami in the first half after entering the concussion protocol and is still awaiting clearance from team physicians to return to football activities. Should he need to sit out Week 13 against the Browns, Dare Ogunbowale and Eno Benjamin would be in line for complementary roles behind top back Dameon Pierce.
