The Bengals scored on a 1-yard run by BenJarvis Green-Ellis and a 2-yard pass from Andy Dalton to Mohamed Sanu while the Raiders looked non-competitive for the most part in the first quarter.
Cincinnati already has plays of 48 yards on a run by Green-Ellis, a 44-yard pass from Dalton to A.J. Green and a 27-yard Dalton-to-Jermaine Grisham completion.
The Raiders have had trouble protecting Carson Palmer and open the second quarter with a first down at the 39-yard line.
