Winters is being evaluated for a concussion and is questionable to return to Sunday's Week 9 tilt against Indianapolis, Calvin Watkins of The Dallas Morning News reports.
Winters went to the blue medical tent in the second half and subsequently headed to the locker room. DeMarvion Overshown (hamstring/back) is inactive Sunday, so Shemar James and Jaishawn Barham could be Dallas' inside linebackers the rest of the way if Winters is unable to return.
