Mitchell (hamstring) was a limited participant in Thursday's practice.
The Chargers put a cap on Mitchell's reps for a second straight day, but his ability to practice in any capacity on consecutive days to kick off Week 1 prep is an encouraging sign for his chances of playing in Sunday's season opener versus the Cardinals. If he's cleared to play against Arizona, Mitchell would likely be in line for a complementary role behind lead back Omarion Hampton.
