DENVER -- The Broncos wrapped up preseason with a 30-2 victory over the Arizona Cardinals at Sports Authority Field at Mile High on Thursday night.
None of the Broncos starters played in the game, which is normal for the final preseason game.
It is the first time the Broncos have gone undefeated in the preseason since 2005.
Third-string quarterback Kyle Sloter played the entire game after backup Paxton Lynch injured his shoulder last week. Lynch is expected to miss a few weeks because of the injury.
Things started slow as Sloter was sacked for a safety in the first quarter, giving Arizona the lead. Later, Brandon McManus hit a 52-yard field goal to make it 3-2.
The action picked up late in the second quarter with the first touchdown of the night. Sloter lead a six-play, 98-yard drive resulting in a touchdown run from Stevan Ridley.
It didn’t take long for the Broncos to extend their lead when Dymonte Thomas, an undrafted rookie out of Michigan, returned an interception for a touchdown to make it 17-2.
Sloter and the offense marched down the field again before the half, setting up a 45-yard field goal for McManus to make it 20-2 at halftime.
After a field goal from McManus, Sloter extended the Broncos' lead with a 21-yard pass to Steven Scheu for a touchdown.
Sloter finished 15 of 23 for 220 yards and one touchdown.
The Broncos have to trim the roster to 53 players by 2 p.m. Sunday. They open the regular season at 8:20 p.m. on Sept. 11 against the Los Angeles Chargers at Sports Authority Field at Mile High.
