Cowboys left tackle Tyler Guyton escaped serious injury in practice Tuesday when the MRI of Guyton's right knee revealed a bone fracture and a sprain.

The Dallas Cowboys suffered what was believed at first to be a devastating blow when left tackle Tyler Guyton went down with a leg injury. Fortunately, it was just a bone fracture that will require a 4-6 week recovery as opposed to the feared torn ACL that would've ended his season.

The Cowboys are using the next man up mentality after the injury to starting left tackle Tyler Guyton. Nate Jones took first-team reps on Wednesday.
