The New England Patriots are having their depth at linebacker tested Sunday.
Starter Dont'a Hightower and reserve Chase Winovich both exited the team's game against the Dallas Cowboys with injuries and are questionable to return, with the Patriots ahead 14-10 early in the second half.
Hightower had two tackles prior to exiting for New England; Winovich had not registered any statistics.
Ja'Whaun Bentley, Josh Uche, Jamie Collins, Kyle Van Noy and Jahlani Tavai remain active for the Patriots as off-ball linebackers.
