SANTA CLARA -– Marcus Martin returned to limited practice on Thursday, and 49ers offensive coordinator Greg Roman said he’s hopeful his rookie center will be available to face the Seattle Seahawks on Sunday.
Martin sustained an injured knee late in the 49ers’ 24-13 loss to the Raiders on Sunday. He did not practice on Wednesday. If Martin is unable to play on Sunday, Joe Looney would get the start.

On Thursday, 49ers offensive coordinator Greg Roman said Martin's play and understanding of the offense been a highlight. Roman said he does not believe Martin has made a mental error in his six starts since taking over for Daniel Kilgore, who sustained a fractured leg Oct. 19 against the Denver Broncos.
Right tackle Anthony Davis must still clear the contact portion of the NFL’s concussion protocol to return to practice. On Thursday, he took part in non-contact work when the 49ers moved their practice to a youth soccer facility in Santa Clara.
Cornerback Chris Culliver, who also sustained a knee injury against the Raiders, is expected to be available after taking part in limited work for the second day in a row. Cornerback Tramaine Brock (hamstring) is expected to miss his 11th game of the season.
