Starting right tackle Marc Colombo has a fractured fibula and he underwent surgery yesterday to repair torn ligaments in his ankle.  The Cowboys will be without Colombo for at least the next six weeks.  Doug Free will likely get the first chance to replace Colombo.  Free has played in 9 games (0 starts) this season for the Cowboys.  In three years with the Cowboys, Free has played in 10 games (0 starts).  This is a huge dropoff for the Cowboys as Free has very little experience in the NFL.
