ARLINGTON, Texas – Three weeks into training camp, the Cowboys got their biggest injury scare of the preseason.

Zack Martin exited in the second quarter of Saturday night's preseason game against Cincinnati with an apparent knee injury. The Cowboys' All-Pro guard took a hit to the knee from Bengals cornerback Dre Kirkpatrick, who went low to avoid  Martin's block on the play.

After stopping briefly in the team's sideline medical tent, Martin left for the locker room and did not return to the sideline. It's worth noting that he returned to the sideline in the fourth quarter wearing street clothes.

There has been no further update on his status to this point, although Cowboys coach Jason Garrett will undoubtedly be asked about his status following the game.

The injury put a damper on what was otherwise a successful showing from the Cowboys' starters. On the possession where Martin was injured, Dak Prescott guided the first-team offense 82 yards in 16 plays, eventually finding Terrance Williams for a six-yard touchdown.

The Cowboys held a 10-0 lead at halftime and had outgained the Bengals, 141-67, in total yardage.
