ARLINGTON, Texas – Cowboys left tackle Tyron Smith headed to the locker room early in the second quarter to get X-rays on his ankle.
Whether Smith will return is not known. He was slow to get up after a Lance Dunbar run in the first quarter but remained in the game for one more snap.
Smith was replaced by Jermey Parnell, who has seen only a handful of snaps in short-yardage situations this season.
