Cowboys OL Allen, Adams hurt
Allen was sidelined for a few plays in the first quarter, but he returned in the second quarter. He then stayed on the turf after blocking on a Dallas field goal attempt that was nullified by a penalty and left again.
Team officials said Allen had a sprained left knee. He was back in the game on Dallas' first drive of the second half.
Adams left the game because of a bruised right shoulder and returned for the next series.
