Dell is questionable to return to Sunday's game against the Broncos with an ankle injury.
Dell didn't draw any targets before he appeared to injure his left ankle on Dameon Pierce's three-yard touchdown run late in the first quarter. Per Aaron Wilson of KPRC 2 Houston, Dell was carted to the locker room, and the rookie wideout is expected to undergo X-rays and scans as the Texans aim to determine the extent of the injury.
