Two 49ers who have missed more than half the season with injuries were back at practice Wednesday.
Tackle Anthony Davis, who suffered a concussion Nov. 16, was a limited participant in his first practice in nearly a month. Davis last week said he was making progress but was still experiencing post-concussion symptoms. That he took part in practice Wednesday means he has one more step to pass – simulated contact – in the league’s concussion protocol before he can be cleared to play in a game.
Meanwhile, cornerback Tramaine Brock went through a limited practice after dealing with a hamstring strain in previous weeks. That injury, plus a turf-toe condition early in the season, has allowed Brock to play in just three games this season. Fellow cornerback Chris Culliver (knee) also was limited, as were guard Mike Iupati (elbow) and nose tackle Glenn Dorsey (forearm).
Center Marcus Martin (knee), wide receiver Stevie Johnson (knee), special teamer Ray Ventrone (groin) and defensive end Justin Smith (back) were in the team’s weight room when practice began and did not take part. If Martin can’t play Sunday, Joe Looney would make his first-ever start at center.

Caution for Bowman – Coach Jim Harbaugh said linebacker NaVorro Bowman, added to the 53-man roster Tuesday, wouldn’t play this week in Seattle but that it was “possible” he will play in ensuing weeks, including if the 49ers make the playoffs.
“Nobody’s going to rush him back out there,” Harbaugh said. “That’s not going to happen.”
Bowman, who is coming back from an ACL injury suffered in January, has not practiced with the team this season and wouldn’t this week, Harbaugh said. Still, he said the Pro Bowl linebacker has been engaged in the team’s day-to-day operations during his recovery.
Et cetera – Harbaugh said the 49ers had an extensive practice Wednesday in case the storm hitting Northern California washed out today’s session.
He said it’s possible the team could hold a walk-through at a nearby hotel ballroom if conditions are bad.
▪ Tight end Vance McDonald, who was placed on injured reserve Tuesday, has a disc issue in his back and will have surgery to correct it, Harbaugh said.
▪ Harbaugh praised the team’s new No. 3 tight end, rookie Asante Cleveland (Christian Brothers High). “He’s done really well,” Harbaugh said. “ He’s excelled in the practices; that’s why he’s been elevated to the 53 (-man roster). I think he can have an impact.”
