"Kicking not a concern

Even though Kris Brown has had two field goals blocked in the last two games, coach Gary Kubiak isn't concerned with Brown being able to convert field goals.

"I thought Kris had been struggling on his kickoffs a little bit, but he kicked the ball much better (at Cincinnati)," Kubiak said. "Our problem with the field goal is protection right now, and that stems from this offensive line issue we have with some of these new young guys coming in.

"We've got to get some extensive work on that this week because that can obviously cost you a game.

"I believe in our kicking game. Our special teams have been good, but we definitely have some things to improve upon."

Mario still ailing

Defensive end Mario Williams has been playing with an injured shoulder.

He's missed practice or has been limited in practice the past two weeks.

"He's close, but I hate to put a number on it," coach Gary Kubiak said when asked if Williams is close to 100 percent. "I just know that it's been bothering him, and it can be an any-given-day deal.

"One day it'll bother him pretty good, flare up on him. Next day, he's OK. "
