ENGLEWOOD, Colo. (AP) — Safety David Bruton Jr. played most of Denver’s game at Pittsburgh with a fractured right fibula that will sideline him indefinitely.

Bruton was injured when he collided with cornerback Aqib Talib with 1:58 left in the first quarter on an incomplete pass to Martavis Bryant.

Bruton stayed in the game and wound up playing a team-high 77 snaps on defense and another 18 on special teams.

Coach Gary Kubiak called it “an amazing gut check,” and said “nobody knew until after the game.”

“It’s amazing what David did,” Kubiak said. “But he’s done it all year long. He’s a leader, he’s a warrior and he gave up everything for his team yesterday.”

The Broncos already were playing without safeties T.J. Ward (ankle), Darian Stewart (hamstring) and Omar Bolden (hamstring).
