Dallas Cowboys running back Tony Pollard suffered a fractured left fibula Sunday that will require surgery, according to sources.

Pollard suffered the injury with 1:24 left in the first half of the Cowboys' 19-12 divisional round loss to the San Francisco 49ers when he was rolled up after an 8-yard catch.

Pollard needed help to the sideline and was wearing an Aircast on his left leg as he was carted to the X-ray room inside Levi's Stadium.

He is scheduled to be an unrestricted free agent in March and had the best season of his career. In 16 regular-season games, Pollard had 1,007 yards on 193 carries. He scored 12 touchdowns this season, surpassing the total he had in his first three seasons. He was named to the Pro Bowl for the first time in his career.
