Broncos' Danny Trevathan back in practice

ENGLEWOOD, Colo. -- Denver Broncos linebacker Danny Trevathan, who was carted off the practice field with a knee injury Wednesday afternoon, was back on the field Thursday with teammates joking about his quick rebound.

Broncos coach John Fox said Trevathan was a full participant in the workout, and the linebacker looked fairly comfortable going through drills during the open period. The Broncos were initially concerned Trevathan’s injury was significant, but an MRI Wednesday afternoon showed no damage, and the Broncos were optimistic Wednesday evening that Trevathan would be able to return to practice. The Broncos will watch him through the week to see how much duty he'll be ready for Sunday in Dallas. Steven Johnson would likely play in Trevathan's weak-side linebacker spot in the base defense if Trevathan did not play.

“I think it was a miraculous recovery," Fox said. “He’s fine and … sometimes in awkward landings in this game, and we were fortunate, he was fortunate."

Broncos kicker Matt Prater was limited Wednesday with a right calf injury -- his kicking leg -- and the Broncos will keep an eye on him through the week.

Wide receiver Eric Decker, who was held out of Wednesday's practice, returned Thursday and took part on a limited basis. The rest of the injury report remained unchanged as cornerback Champ Bailey (left foot) and linebacker Paris Lenon (thigh) were limited. Tight end Joel Dreessen (knee), center Manny Ramirez (ribs), defensive tackle Mitch Unrein (neck), and guard Chris Kuper (ankle) all participated fully.
