Training camp report: Fan fest, the not-so-good — Delanie Walker hurts his knee

SAN FRANCISCO – Delanie Walker left practice early with a right knee injury. He got tangled with Ian Williams when he was blocking and he fell to the ground in pain.

He stayed on the ground for a couple minutes, and then he stood up and took several more minutes before he slowly walked off the field. He watched most of practice sitting on the bench, and the right knee was heavily braced.

Aldon Smith did not attend practice today. Jim Harbaugh said that he expects Smith to miss “about a week.”

Harbaugh said that the 49ers “dodged a bullet” with Aldon Smith’s injury, and he said he feels the team probably dodged another one with Walker’s knee. He doesn’t expect the tight end to miss a lot of time.
