San Francisco 49ers

Marcus Lattimore to begin training camp on PUP list

Jim Harbaugh said the 49ers “hit it out of the park” when it came to Wednesday’s conditioning test with everyone receiving a passing grade. But a number of players, including one prominent young player and four draft picks, didn’t take part due to injuries.

That list includes running back Marcus Lattimore, who will begin training camp on the physically-unable-to-perform list. Harbaugh said that team doctors evaluated Lattimore and “we do what’s best for the member of the team.”

Asked if the issue is with Lattimore’s surgically reconstructed knee or the hamstring strain that bothered him in the spring, Harbaugh said, “a combination of the two” before referring questions to team doctors, who are off limits to the media.

Also out of action to start camp are draft picks Marcus Martin, a center, Bruce Ellington, a wide receiver, Aaron Lynch, an outside linebacker and Kaleb Ramsey, a defensive lineman. Lynch hurt his hamstring in the spring while Ellington and Martin suffered minor ankle injuries away from the team facility during the recent break. Ramsey’s injury is unknown. Harbaugh said none of the rookies are expected to miss much time with Ellington returning the soonest.

Additionally, tight end Garrett Celek hurt his back, Harbaugh said, and is having an MRI today to determine the seriousness of the injury.
