The 32-year-old linebacker leveled receiver T.J. Houshmandazeh after he caught a 12-yard pass on the Bengals' second play of the game. Lewis got up holding his arm in pain.
He finished the series, then came to the sideline and got a stretch wrap applied to his upper arm. Lewis played the next series, but shied away from contact with the arm.
Lewis later jogged to the locker room to get the arm examined while Carson Palmer threw a 39-yard touchdown pass to Chad Johnson. Lewis had joked with Johnson that he wouldn't get into the end zone against the Ravens.
Lewis returned after getting his upper right arm tightly wrapped. During his next series, Lewis pulled down Rudi Johnson with his opposite arm, clearly favoring the injured one.
Graham returned and kicked a 23-yard field goal that made it 9-0 later in the first quarter.
