Cousins perfect in Minnesota debut, Vikings beat Broncos

Von Miller will play in Broncos first preseason game

Kirk Cousins, the free-agent splash of the offseason, was ideal in his cameo, including a gorgeous, tight-windowed 28-yard completion to Stefon Diggs, in the Vikings' 42-28 preseason win over the Broncos on Saturday.

Case Keenum wasn't almost as sharp in his Denver debut, completing just 1-of-4 passes for 5 yards spanning two drives.

Siemian, who began his career with the Broncos, came on to hit on 11 of 17 passes with one interception.

Keenum wasn't the only Broncos quarterback whose performance was lacking against the Vikings.

Kelly threw a 36-yard touchdown pass to tight end Matt LaCosse to pull Denver to 27-21 and amid chants of "Kelly!" Sloter also ran 14 yards for a score with about three minutes left in the game.

Sloter was 9 of 11 for 69 yards and Kelly was 14 of 20 for 176.

Cousins completed all four of his passes, which included a 1-yard touchdown to Diggs on a quick slant, but the dart to the newly well-paid wide receiver was the most encouraging play.

Lynch might be losing in his battle to be the backup, but he insisted he's "excited for Chad".

Broncos coach Vance Joseph wasn't quite ready to elevate Kelly to No. 2 QB, saying he had to study the film. "Obviously Case is the starter, so that's my main concern". He played well tonight, outside of the one interception, which led to a score for those guys. There are a lot of new players on the team. "That's a good deal". Last year, Joseph stuck with McKenzie despite half a dozen fumbles. "He's obviously a talent. We're helping him fix that so he can help us win games".

Marshall and Thomas emerged from the tunnel behind the Broncos' bench after the anthem was over.

"We didn't know about that", Joseph said.

Broncos S Jamal Carter left in the second quarter with a hamstring injury.
