Manning improved to 8-0 career against Cincinnati (3-5), which has lost four in a row for the first time in two years. This win didn't come so easily.
The four-time MVP threw two interceptions -- one in the end zone -- that led to 10 points and a 20-17 Bengals lead early in the fourth quarter.
That's when the Broncos (5-3) have been at their best.
Manning threw a 1-yard touchdown pass to tight end Joel Dreessen to put Denver back in front. After Andy Dalton underthrew an under-pressure pass that was picked off by Champ Bailey, Manning put it away with a 4-yard pass to Eric Decker with 3:36 remaining.
