The 49ers held practice this morning during their mandatory minicamp. Every player on the 49ers' roster is accounted for. Most are practicing. Only Michael Crabtree (foot), Arnaz Battle (foot), Ray McDonald (knee), Walt Harris (knee), Shawntae Spencer (knee) and Clements (pneumonia) are not taking part in the practices.

Clements will be evaluated on Monday to determine whether he can return to practice during organized team activities.

Crabtree is scheduled to step on the field to practice for the first time when the 49ers open training camp, most likely on July 30. Singletary said he does not want Crabtree to do anything that might lead to a setback before then.

"I don't even want to try to get him out there," Singletary said. "I want him to do everything he's supposed to do, so when it's time to go, he's ready to go. I want him to stay with Jerry Sullivan as much as he can. When (receivers coach) Jerry Sullivan goes to sleep, I want him to have to tell Crabtree to get out."
