Dallas nose tackle Jay Ratliff suffered an apparent left leg injury late in the first half of Sunday night's game against the Atlanta Falcons.
Ratliff was attempting to put pressure on Falcons linebacker Matt Ryan when he pulled up, favoring his left leg, before falling to his knees.
The Cowboys called timeout to assist Ratliff on the field. He was able to walk off the field.
There was no immediate report from the Cowboys on Ratliff's status.
Ratliff was in uniform when he slowly walked to the Cowboys sideline as the second half started.
Falcons defensive tackle Peria Jerry left the game in the second quarter with a knee injury. The Falcons say his status is questionable.
