Marvel Smith visiting San Francisco
Posted by ESPN.com's James Walker
Smith played mostly left tackle for the Steelers but could be asked to play on the right side in San Francisco due to the presence of left tackle Joe Staley. Pittsburgh already made four signings to keep its offensive linemen and Smith doesn't appear to be in the Steelers' plans.
One selling point for the 49ers is that Smith grew up in nearby Oakland. San Francisco is looking for offensive line help through either free agency or the draft.
