NFL injury report: Willis McGahee headlines the injured

After coming into this weekend with quite the healthy roster, the Denver Broncos saw one of their most important players go down on Sunday. Starting running back Willis McGahee tore his MCL and also suffered a lower leg bone fracture in the Denver Broncos' victory against the San Diego Chargers, and ESPN reports that McGahee will miss six-to-eight weeks, though the injury will not require surgery.

The Broncos aren't placing the running back in injured reserve because if all goes well, McGahee could be able to return in four-to-six weeks, according to ESPN.

Still, the team worked out running backs on Monday, including former Houston Texans back Steve Slaton. Head coach John Fox did not say the team was set on signing a back, telling the team's website that he has confidence in backups Ronnie Hillman, Lance Ball, Knowshon Moreno and even practice squad player Jeremiah Johnson.

Defensive end Elvis Dumervil played Sunday after coming in as questionable because of a shoulder injury. He had six tackles, a sack and a forced fumble against the Chargers.

Cornerback Tracy Porter was again out with illness as he continues to be monitored for seizures.
