The Chargers have placed tight end Antonio Gates on the physically-unable-to-perform list, which allows him to do rehab work and take part in team meetings but not practice.
Gates has plantar fasciitis in his right foot. He has done sprints and agility works on a side field since training camp opened Thursday.
Gates missed six games last year because of the plantar fasciitis, inflammation in the heel and the bottom of the foot. His injury included a tear in the foot.
Gates can be moved to the active roster at any time.
The Chargers also placed outside linebacker Larry English, who is coming off foot surgery, on the list. English, a first-round draft pick in 2009, started two games last season.
"When they're ready to start practicing, we'll get them back on the field," coach Norv Turner said. "We're going to spend the next period of time getting them ready so when we get them on the field, they can stay on for an extended period of time."
