Peyton’s replacement throws for four TDs, singes Cincinnati

CINCINNATI — Four touchdown passes, more than 300 yards passing, two clutch touchdown drives in the fourth quarter.

Trevor Siemian played every bit like Peyton Manning in his first road start. In some ways, even better. Siemian was nearly perfect as he rallied the Denver Broncos to a 29-17 victory over the Cincinnati Bengals on Sunday, leading a pair of fourth-quarter touchdown drives with veteran aplomb.

The defending Super Bowl champions’ biggest offseason challenge was replacing their famous quarterback, and it looks as if they made the right choice. They’re 3-0 under Siemian, who took over after Manning retired and Brock Osweiler went to Houston. ■ KEY: Trevor Seimian threw two of his four touchdown passes in a span of 2:33 in the fourth quarter, rallying the Broncos to a road victory. ■ NEXT: Broncos (-2½) at Buccaneers, 1:05 p.m. Sunday; Dolphins at Bengals (-7), 5:25 p.m. Thursday

Siemian became the first Bronco to throw for four touchdowns since Manning in 2014 against the Dolphins. No NFL quarterback had thrown for 300 yards with four touchdowns and no interceptions in their road debut, according to ESPN Stats and Info.

“Obviously going in, nobody really knew about him,” said Emmanuel Sanders, who caught the first two touchdowns. “Now everybody’s starting to talk about him. He’s always calm, cool and collected, even in the fourth quarter. You should have seen the way he took command in the huddle.”
