While he's not one of the three first-round picks on the offensive line, Ron Leary is a big reason for the Cowboys' success in the running game. And that is why the team had to be somewhat concerned when Leary left the game in the fourth quarter with a head injury.
He underwent the NFL's concussion protocol tests. Head coach Jason Garrett didn't have any other information on the injury.
The Cowboys will monitor his injury throughout the week and update his chances of playing next week in Pittsburgh.
Guard Joe Looney, who is also the team's backup center, filled in for Leary at the end of the game.
