Danny Trevathan's injury is different this time

A lot of people saw Denver Broncos linebacker Danny Trevathan carted off the field Sunday with a left leg injury and assumed he had been rushed back to the field too soon. After all, he missed seven weeks in the preseason and regular season when he cracked a bone below his left knee in training camp, and he had only been back one previous game. Presumably he suffered a setback to the same fracture in his leg.

It turns out that isn't the case. Trevathan's new injury is a crack in the bone above and to the side of his knee, while his previous injury was below and to the front, head coach John Fox said Monday.

Trevathan has a crack in the bone "just above the knee" in his left leg. "Nothing remotely the same" compared to his last injury, Fox said.

Random and unlucky? Maybe. Caused by Trevathan favoring his legs different post-injury? Possibly. But different nonetheless.

Fox said the Broncos didn't want to give a timeline but said they and Trevathan will take it "one day at a time." That being said, The Denver Post's Mike Klis notes that leg fractures generally take six weeks to heal.

Fox said the team will give an update to Trevathan's game availability Wednesday. So we continue to wait. In the meantime, linebacker Brandon Marshall will continue to fill in for Trevathan as the Broncos' primary weakside linebacker while Corey Nelson and Nate Irving play supporting roles based on what Jack Del Rio coordinates defensively. Nelson had 36 snaps Sunday, earning him an MHR Game Ball, while Irving had 16.

Update: Klis reports that Trevathan will be out 3-6 weeks.
