The Dallas Cowboys have already been dealing with injuries at the cornerback position this offseason, and they lost more depth this week.

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.

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.
