ENGLEWOOD – Rookie safety Darcel McBath broke his right forearm on Sunday against Indianapolis and is done for the season, Broncos coach Josh McDaniels said Monday.

McBath, who was placed on injured reserve, was Denver’s first safety off the bench – he intercepted Colts quarterback Peyton Manning on Sunday – and one of the team’s best special teams players. McBath leads the Broncos in special-teams tackles, with 11.

“He’s been a big part of our special teams,” McDaniels said.

The Broncos will sign safety Vernon Fox, who played 10 games with Denver last year. One of McBath’s most important roles was as the “personal protector” on the punt team, the position just behind and offset from the long snapper who makes the calls. Fox also played that position in preseason, before he was released, and could take that role.

“He’ll be missed in that sense,” McDaniels said.

McDaniels didn’t offer many updates on other injured players, although he said Peyton Hillis could be in line for more playing time if Correll Buckhalter can’t play this week. Buckhalter left the stadium after Sunday’s game on crutches after suffering an ankle injury.
