Injuries continue to pile up along the Dallas Cowboys offensive line following Tyler Guyton's knee injury, a day after guard Rob Jones broke a bone in his neck during training cam

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.

Guyton, a first-round pick out of Oklahoma, started 11 games and played in 15 as a rookie last season. The Cowboys have been counting on the 6-foot-7, 325-pound Guyton taking a step forward in his second season as part of a reconfigured offensive line.
