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.

An MRI revealed that Cowboys left tackle Tyler Guyton suffered a bone fracture -- not a torn ACL -- in his right knee during Monday's practice. He will miss 4-6 weeks but the injury will not require surgery.
