Texans WR Johnson injures hamstring

Houston receiver Andre Johnson has left the Texans' game against the Steelers with a right hamstring injury.

Johnson caught a 13-yard pass in the second quarter and was holding the back of his right leg near the knee after he fell to the ground. He pulled up at the end of the play, but was not hit.

He remained on the field and was looked at by trainers before gingerly walking off on his own power.

He then walked to the locker room with members of the training staff.

The team says his return is questionable.
