Cowboys OL Zack Martin to Have MRI on Knee After Exiting Preseason Game

Cowboys offensive lineman Zack Martin will have an MRI on Sunday after exiting the Cowboys-Bengals preseason game with a knee injury Saturday, the team announced. Martin left the game only two minutes into the second quarter and did not return. The Cowboys were running a sweep play to the right, and Martin was cut low while pulling on a block by Bengals defender Dre Kirkpatrick.
