Cowboys owner Jerry Jones is worried about injured running back Felix Jones.
Jerry Jones told ESPN that his running back was not able to loosen his left knee after leaving Monday night's win against Carolina.
Felix Jones had 114 yards yards from scrimmage on nine touches, but did not finish the game. Dallas was already playing without Marion Barber, so Tashard Choice was the lone healthy tailback by the end of the game.
After just six games last year as a rookie, Felix Jones landed on IR with a toe injury. And he suffered a strained quad in Week 1 this season.
The running back is expected to have an MRI today. Wade Phillips may have more on his status at his afternoon news conference.
