DALLAS (105.3 The Fan) - All-Pro left tackle Tyron Smith exited Sunday night's Cowboys-Vikings matchup after re-injuring his left ankle in the first half.
Smith was seen with the medical staff on the sideline without his helmet, while reserve tackle Ty Nsekhe took his place in the lineup. He is questionable to return.
Smith initially suffered the injury against the Patriots in Week 6 but was able to return to the game.
The Cowboys do have former starting right tackle La'el Collins available to them Sunday night after he missed the previous five games while serving a suspension for violating the league's substance-abuse policy.
