Right tackle Marc Colombo went down midway through the first quarter after his left leg was rolled up by the Packers' Johnny Jolly on the back end of a sweep. As anyone who saw Fox's slow-motion replay probably surmised, this was a potentially nasty injury.
The early report had team officials describing the injury as a "bad high ankle sprain," a time-consuming and all too common injury among linemen. However, it may be worse than that.
NBC-DFW's Matt Barrie has reported from Green Bay that Colombo suffered a broken left fibula.
The Cowboys are one of only six teams in the NFL to have started the same five offensive linemen in each game this season, a distinction that may be in jeopardy with the injury to Colombo.
