Projected Cowboys starter suffers apparent lower-leg injury at end of practice

In this story:
The Dallas Cowboys held their second practice in pads on Monday during training camp in Oxnard, California.
A culture shift has been obviously present throughout the entire camp with first-year head coach Brian Schottenheimer leading the charge.
But there were no good vibes from the current coaching staff that could help the scene fans saw near the end of Monday's practice session after Tyler Guyton went down with an apparent lower-leg injury.

The positive note for the Cowboys and Guyton is that he was able to walk off of the field and to the locker room under his own power, flanked by superstar defender Micah Parsons and the training staff, while offensive line coach Conor Riley provided words of encouragement.

An injury to Guyton at this stage of camp would be brutal for the 2024 first-round pick and the Cowboys -- who learned earlier in the day that veteran lineman Robert Jones would miss extended time after suffering a broken bone in his neck during the team's first practice in full pads over the weekend.

Guyton was ready to put his rocky rookie season behind him. Now, he has to hope that this potential injury isn't going to cost him any serious time.
