It was a rough two-day stretch for the Dallas Cowboys on the offensive line. After Robert Jones broke a bone in his neck during Sunday's training camp practice, Tyler Guyton left the field Monday with a knee injury.

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

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.
