The battle has been won at sold-out Paul Brown Stadium.
The victor is the Bengals, who are 8-0 with a 31-10 Thursday night win over the Cleveland Browns in Battle of Ohio I.
It was quite a night for the Dalton-to-Eifert connection.
Dalton threw three touchdown passes to Eifert, and played lead blocker on Mohamed Sanu's 25-yard reverse for a fourth-quarter touchdown, giving the Bengals a 24-10 lead.

There was no let down after the big road win in Pittsburgh against the Browns (2-7).
Coming off an emotional 16-10 victory over the Steelers on Sunday that gave them control of the AFC North, the Bengals dominated the Browns and quarterback Johnny Manziel in the second half.

Dalton finished 21-of-27 passing for 234 yards. Eifert's three touchdown catches gave him nine for the season, tying the club record for a tight end. He totaled five catches for 53 yards.
Kicker Mike Nugent booted a 23-yard field goal to make it 17-10 in the third.
Eifert caught TD passes of 9 yards in the opening quarter, 2 yards in the second, and 19 yards in the fourth while helping set the final score.
The Bengals outgained the Browns in total yards, 371-213. Cincinnati had 23 first downs compared to 13 for Cleveland.
Manziel finished 15-of-33 passing for 168 yards and a 12-yard second-quarter TD pass to running back Duke Johnson that helped whittle the Bengals' lead to 14-10.
Johnson caught a pair of passes for 32 yards and ran three times for no yardage. Backfield mate Isaiah Crowell led the Browns with 38 yards on 10 carries.
