DENVER -- The Giants shocked the Broncos as Denver fell to previously winless New York, 23-10, on Sunday night at Sports Authority Field at Mile High.

After a loss earlier Sunday by the Oakland Raiders and Kansas City Chiefs, the Broncos had an opportunity coming off of their bye week to gain some ground in the AFC West battle.

The Broncos got the ball first and it was a quick three-and-out for the offense. Despite being 0-5, the Giants came to play as they drove to the red zone and scored first with a 25-yard field goal.

It was the first time this season the Broncos allowed an opponent to score on its opening drive.

The Broncos' first scoring opportunity didn't come until late in the first quarter. But Brandon McManus' 35-yard field goal attempt was wide right.

The Giants continued to own the Broncos as they marched down the field for the first touchdown of the game to make it 10-0 in the second quarter.

Trevor Siemian was intercepted by Landon Collins on third down in the second quarter. The pass was intended for Demaryius Thomas, who was sandwiched between two Giants defenders.

Justin Simmons and the Broncos defense prevented things from getting worse by forcing the Giants to go three-and-out on the drive.

After a big gain from Thomas, the Broncos were finally able to score with a 28-yard filed goal from McManus to make it 10-3.

As halftime approached, Siemian threw his second interception of the game. This time, Janoris Jenkins returned it for a touchdown to give the Giants a 17-3 halftime lead.

Siemian hurt his left shoulder while trying to make a tackle on the interception. Siemian went to the locker room and Brock Osweiler made his 2017 debut for the Broncos with less than a minute left in the half.

Osweiler's time was short-lived as Siemian returned to the game in the second half, but things continued to go bad for the Broncos.

On a first down, Siemian was sacked for an 11-yard loss  and McManus' 53-yard field goal was blocked by the Giants.

Later in the third quarter, things got worse for the Broncos when Emmanuel Sanders took a helmet to the knee and had to be carted off to the locker room. He was ruled out for the remainder of the game.

Another receiver went down for the Broncos a few minutes later when Isaiah McKenzie had to be carted off the field after an apparent leg injury.

X-rays for Sanders and McKenzie came back negative and both will have MRIs on Monday, coach Vance Joseph said after the game.

The Broncos finally scored their first touchdown of the game in the fourth quarter with about four minutes left in the game. Siemian found Jeff Heuerman in the end zone to make it 20-10.

It didn't matter though, as the Giants stayed in control and added another field goal to get their first win of the season.

The Broncos drop to 3-2 and play their next three games on the road -- at the Los Angeles Chargers, at Kansas City and at Philadelphia.
