After sustaining the injury Phillips, who injured his right knee last season, at one point was laying on the ground while getting attention from trainers.

Dolphins edge rusher Jaelan Phillips, whose past two seasons ended prematurely with major injuries, left practice Saturday with what appeared to be a left knee injury. He gave fans a thumbs up as he departed but he was walking gingerly. Last season, he sustained a season-ending torn ACL in his right knee.

The Miami Dolphins held Day 9 of training camp practice but Jaelan Phillips did not make it through the workout. And Austin Jackson is out.
