Brandon Marshall has performed admirably in place of Danny Trevathan at weakside linebacker. But the Broncos are best when Trevathan is their three-down linebacker, Nate Irving is their base linebacker and Marshall is a nickel linebacker.

Without Trevathan, Irving plays more in nickel and Marshall more in base. When Trevathan fully returns from his leg injury, order will be restored to the Broncos’ linebacker core.

“I’m anticipating he’ll be there Tuesday,” Broncos coach John Fox said.

Trevathan said he would be at about 75 percent for practice Tuesday. His goal is to be ready to play in the Broncos’ next game, Oct. 5 at home against Arizona.
