The Indianapolis Colts announced on Tuesday that quarterback Andrew Luck sustained multiple injuries during Sunday's win over the Denver Broncos that will keep him out for several weeks. Those injuries include a lacerated kidney and a partial tear of his abdominal muscle, per the Colts' official website.

"The injuries happened at the end of an early fourth-quarter scramble when Andrew was doing everything he could to get us the win," head coach Chuck Pagano said. "Andrew was sore after the game and was feeling a little worse Monday afternoon so we sent him to get tests."

Per the Colts, it is not yet known how long Luck will be out, but the injuries will take two to six weeks to heal.

The win over the Broncos was by far the biggest of the season for Indianapolis, which had struggled badly through the early part of the year. Luck in particular had some poor performances, specifically against the Bills and Jets in the first two weeks of the year. He also sat out games against the Jacksonville Jaguars and Houston Texans with a shoulder injury, and was reportedly playing with cracked ribs as well.

Without Luck, the Colts will have to turn to backup QB Matt Hasselbeck, who also filled on for the Jaguars and Texans games, acquitting himself fairly despite being sick during the week leading up to the Houston game.

The Colts, who will take their bye this coming Sunday, have the Falcons, Buccaneers, Steelers, Jaguars, Texans, and Dolphins coming up in the next six games on their schedule before they take on the Titans in the season finale. They're currently in first place in the AFC South at 4-5, one game ahead of Houston.
