The Cowboys will get a chance to test the quality of their offensive line depth following injuries to Tyler Guyton and Rob Jones.

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.

According to multiple reports, Guyton has a broken bone in his right knee that will not require surgery and he could miss four to six weeks. The Cowboys open the season at the Philadelphia Eagles on Sept. 4, meaning a recovery on the longer end of that timeframe would put Guyton's availability in question for that NFC East game.
