SANTA CLARA, Calif. – It appears the San Francisco 49ers will travel to Tampa Bay at near full health.The biggest injury question is whether left guard Mike Iupati will return from a sprained knee. He's missed the past three games. He has practiced on a limited basis all week. 49ers coach Jim Harbaugh said Friday it's possible that Iupati can play Sunday. If he can't, Adam Snyder will make his fourth straight start.Receiver Michael Crabtree is probable with an ankle injury that he tweaked against Seattle last week.
