Cowboys starting left tackle Tyler Guyton sustained a bone fracture in practice that will not require surgery and he is expected to miss four to six weeks, NFL Network Insider Ian Rapoport reported.

Tyler Guyton was feared to have suffered a torn ACL at Cowboys training camp Monday. However, an MRI revealed the ligament is intact.

The loss of Guyton for an extended period could have been devastating, considering medical officials first made sure his ACL was secure. Once that ligament was declared in good shape, further examinations revealed the fractured bone and sprain in the knee.
