Dallas Cowboys All-Pro guard Zack Martin left Sunday night’s game during the offense’s second possession after getting his left knee rolled up during a play.
Martin has been nursing for a sprain in the same knee for a month. The Cowboys replaced Martin with Adam Redmond, who has played in three NFL games. Both guards for Dallas are playing in their first games this season. Xavier Su’a-Filo started in place of left guard Connor Williams, who was injured last week against Tennessee.
Su’a-Filo has played 56 games (41 starts) for the Texans after being drafted in the second round in 2014.
