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 camp. While Guyton's situation is not season-ending, the projected starter at left tackle is questionable for Week 1 with a 4-to-6 week timeline for a return.

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

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.
