Those looking to make the Carolina Panthers' roster at training camp have no margin for error. Everything must go according to plan, or better than expected, to secure their spots before Week 1 against the Jacksonville Jaguars.
And for one veteran on the brink, he's already playing catch-up after an early setback.
The Panthers placed wide receiver Dan Chisena on the active/physically unable to perform list before camp begins. The exact nature of the injury wasn't disclosed, but the fact that he can be activated at any stage suggests that it's not too serious.
