John Fox has no problem with nose tackle Terrance "Pot Roast" Knighton's Super Bowl bravado.

"I think that's been the goal all season," the Denver Broncos coach said when asked for his take on Knighton's Joe Namath-like guarantee over the weekend that Denver will win it all.

"I think guys said it way back. The key - and they understand this - is how we get there," Fox said. "We've been pretty good all season long at keeping our focus small. All our focus will be on the Cincinnati Bengals."

The Broncos (11-3) can secure a first-round bye and keep the heat on New England for the No. 1 seed in the AFC by beating the Bengals (9-4-1) Monday night.

Even amid news that linebacker Danny Trevathan's season was over because of a dislocated kneecap and word that defensive MVP Brandon Marshall (foot) would be sidelined until the playoffs, Knighton wasn't backing down from his promise.

Kosar rips Browns

Bernie Kosar, the Browns' best quarterback in the last 30 years, said that the team's front office lacks vision and that switching to rookie Johnny Manziel "is a recipe for disaster."

Kosar delivered a harsh critique of his former team in an interview with Cleveland's WTAM radio Monday. Kosar, whose contract as a preseason TV analyst was not renewed last summer, said the Browns' current regime doesn't "know how to lead and organize and set a culture to play winning football."

Manziel made his first start Sunday and played poorly in a 30-0 loss to Cincinnati. Kosar called the Browns' constant rotation of quarterbacks part of a "systemic" problem within the organization.

Chargers lose Allen

Keenan Allen, the San Diego Chargers' leading receiver, has a broken right collarbone, the team said.
