The 49ers began their second practice of the week without their two starting tackles, Anthony Davis and Joe Staley. Davis still is recovering from a concussion suffered 17 days ago. He was working out in the team’s weight room, the last step before a concussed player returns to practice.
Staley’s status is unknown. (Jim Harbaugh will address the media at 1:10 p.m.) *UPDATE* Harbaugh said Staley was dealing with a stomach bug
Also absent were tight end Vance McDonald (back), Tramaine Brock (hamstring) and defensive end Justin Smith (back), who typically does not practice on Wednesday. McDonald’s absence signals another game in which the 49ers’ tight ends are Vernon Davis, Garrett Celek and undrafted rookie Asante Cleveland (Christian Brothers).
Cornerback Chris Culliver and running back Carlos Hyde were wearing blue, no-contact jerseys for the second straight practice.

Receiver Michael Crabtree and defensive end Ray McDonald both were injured in Thursday’s game against Seattle and sat out a number of plays. Both, however, were on hand for the start of today’s session.
For what it’s worth, head coach Jim Harbaugh and general manager Trent Baalke were seen chatting amicably as the session got under way. The 49ers typically practice at 2 p.m. Today’s session was moved to 11 a.m. because of the rain.
