Willis McGahee tore his MCL and will miss 6-8 weeks with the injury and also has a fractured leg, says Jay Glazer of FoxSports.
Those injuries mean that McGahee is probably done for the remainder of the regular season and perhaps for the year, unless the Broncos can make some sort of deep postseason run, which is a possibility.
McGahee went out early in Sunday's win over the San Diego Chargers.
