With Nick Ekbatani (left knee) and Jess Ward (right knee) already on the sidelines with MCL injuries, redshirt junior defensive end Reginald Stokes was carted off Spaulding Field on Sunday with a swollen right knee after sustaining contact during the first 11-on-11 drill of the day.

Stokes didn’t return to practice, creating even more depth issues along UCLA’s defensive line.

“(Trainers) said his knee swelled up pretty badly,” coach Rick Neuheisel said. “It’s too bad because he’s had a nice camp and he’s been a good player for us. But he’s a tough guy. He’s been knocked down and come back before.”

Also missing most of Sunday’s practice, although not for injury-related reasons, was redshirt freshman defensive tackle Justin Mann.

Early in practice, Mann had to be attended to by team trainers, then campus paramedics and eventually L.A. Fire Department paramedics, who treated him for heat exhaustion and a low blood sugar level.

Mann, who had his blood pressure taken and was administered oxygen on site before being taken off the field by paramedics for more extensive tests, returned near the conclusion of practice walking around on his own power wearing a T-shirt and shorts.
