Ferguson (concussion) participated in Wednesday's walk-through session, David Moore of The Dallas Morning News reports.
The Cowboys host the Bengals on Monday night in Week 14, so the team won't issue its first injury report until Thursday. Nonetheless, it was a positive sign for Ferguson's likelihood of returning to game action that he was able to take part Wednesday in what Moore deemed a "mock game." Ferguson has missed both of the Cowboys' past two contests after suffering a concussion Week 11 against Houston, and though he was on the field Wednesday, it's not yet certain whether he's cleared the NFL's five-step concussion protocol.
