Kyle Shanahan made it out to the practice field for about 30 minutes Sunday afternoon. The 49ers coach is still recovering from a car accident that left him with cracked ribs, a broken nose, a black eye and a concussion, but players knew he wouldn’t be able to stay away for the first drills of training camp.

“The guy is obsessed with ball, so of course he’s going to be around,” linebacker Fred Warner said.

At the end of practice, the team gathered around and heard an impassioned salute from assistant head coach Chris Foerster, 64, who is running training camp while Shanahan is on the mend — with the help of the coordinators and some of the players themselves.

“I just love this football team,” he said. “I love how hard they work, the energy, the effort. By far we have a reason to come out and practice tomorrow — we’ve got a lot more work to do — but I really love the energy and the attitude of the guys when they come to work.”
