The Cincinnati Bengals are on course to make it a perfect season at home as they have taken a 17-6 lead into half time of their match against the Baltimore Ravens.
The Ravens took the lead on their first possession as Andy Dalton threw an early interception to set up a 38-yard field goal attempt that Justin Tucker duly converted.
Dalton threw another interception to gift Baltimore the ball back again late in the quarter, and the result was the same as Tucker doubled his side's advantage with a 22-yard kick.
The Bengals quarterback recovered from those setbacks before the end of the opening quarter, however, throwing a huge 53-yard touchdown pass to a wide-open AJ Green for the first touchdown of the match to put the hosts in front.
They extended their lead in the second as Mike Nugent successfully kicked a 39-yard field goal to open up a four-point gap.
Four became 11 courtesy of a touchdown just before half time, Dalton throwing a 16-yard pass down the middle for Marvin Jones, who collected it brilliantly inside the endzone with one hand.
