This article was updated to include the results of Trevathan’s MRI.

Bad news from Broncos camp: Linebacker Danny Trevathan fractured his left leg while practicing in full pads with the team Tuesday morning, ESPN reports. He is expected to miss the next six to eight weeks of action.

Trevathan, who had a team-leading 124 tackles last year for the Denver squad, told ESPN’s Josina Anderson:

“They told me that my ACL and MCL are fine, but that I have a fracture in my knee. The doctor told me I was going to be out four to eight weeks, but I told him four to six. I’m not tripping. I will bounce back. I’m a soldier.”

It was later confirmed via an MRI that Trevathan sustained an impaction fracture to the medial tibial just below his left knee, ESPN reports.

“You never like to see any player go down,” coach John Fox told ESPN. “We’ll wait and see what the results say. I didn’t have a clean view of it. … It was away from me so I didn’t see it.”

The injury occurred during a run play, which took the third-year player to the ground where backup center Will Montgomery rolled over him, according to ESPN. Trevathan immediately grabbed his left knee and was eventually carted off the field.
