Cooks (undisclosed) was not listed on Wednesday's injury report.
Cooks was spotted entering the X-ray room with trainers after Buffalo's win over the Patriots in Week 15, but he appears to have only been receiving a precautionary examination. The veteran wideout didn't record a catch versus New England, but his three targets were the second most on the team. He'll continue operating as a depth wideout for Buffalo in Sunday's road matchup against the Browns.
