CENTENNIAL, Colo. -- The Broncos' secret weapon in the run game walked unnoticed through the locker room Wednesday.

Andy Janovich wore a brace on his right hand, a hint of the violence he inflicts on the field. The Broncos rushed for a season-high 190 yards in Monday's win over Houston. There were several reasons: terrific offensive line play from center Matt Parardis and guards Max Garcia and Michael Schofield. On point audible work by quarterback Trevor Siemian. Slick and powerful bursts from C.J. Anderson and rookie Devontae Booker.

And the lead blocking of Janovich. Or maybe we should just call him 'Manovich.'

The rookie punishes defenders. And equipment. Janovich has busted four facemasks and cracked two helmets this season.

The Broncos, in one game, called a timeout to fix Janovich's helmet so he could return without missing a play.

Andy, you have some explaining to do.

"It's hard to explain. I can usually tell. You know the facemask is broken when it falls down over your face," Janovich told Denver7.

The hits have become a badge of honor for Janovich. He began cracking helmets and breaking facemasks at Nebraska. Too many to remember. The Broncos have learned.

"Now they have a second helmet on the sidelines ready just in case," Janovich said.
