ENGLEWOOD, Colo. -- The Denver Broncos received positive news on linebacker Danny Trevathan, who was carted off the practice field Wednesday with a knee injury.
An MRI later Wednesday afternoon revealed no significant damage that would require a long absence. Trevathan remains a question mark for Sunday's game in Dallas.
However, early Wednesday evening, team officials expressed optimism that Trevathan could return to practice during the week and, if things go well over the next few days, could be in uniform against the Cowboys.
Trevathan is the Broncos' second-leading tackler, with 30, and is a key part of the team's plans in pass defense. The speedy linebacker is consistently asked to match up on opposing tight ends in pass coverage.
And that's a significant part of the Cowboys' passing attack, given that Dallas quarterback Tony Romo has completed 46.4 percent of his passes to the team's tight ends and running backs. Cowboys running back DeMarco Murray and tight end Jason Witten each have 21 receptions in four games.
"Danny went down; we hope for the best," Broncos linebacker Nate Irving said. "If he can't go Sunday, we all have to be ready to step up."
