ARLINGTON, Texas — Detroit Lions rookie guard Travis Swanson was helped from the field in the first quarter of Sunday’s NFC Wild Card game at Dallas.

Swanson was treated for a knee injury on the sideline and was taken to the the locker room for further evaluation. His return is questionable. Swanson started at right guard with Larry Warford (ankle) inactive.

Lions cornerback Rashean Mathis left the game with a quadriceps injury. His return is also questionable.

Cowboys inside linebacker Rolando McClain was taken to the locker room to be treated for dehydration. McClain did not travel with the team to Washington for the Week 17 game last week because of an illness.
