49ers News: OT Anthony Davis Out With Concussion, Jonathan Martin To Start

The San Francisco 49ers will be without offensive tackle Anthony Davis once again when they host the Seattle Seahawks on Thanksgiving night.

Per Matt Maiocco of CSN Bay Area, "Jonathan Martin will make his seventh start at right tackle this season, as the 49ers ruled out Anthony Davis from playing Thursday’s game against the Seattle Seahawks with a concussion."

Davis missed the 49ers' entire offseason program after offseason shoulder surgery. He has missed time with both hamstring and knee injuries this season, along with Thursday being his second-straight game missed with a concussion (suffered on the final play of the team's victory over the New York Giants on November 16th).

Davis joins third-string tight end Derek Carrier (foot) and defensive tackle Glenn Dorsey (forearm) as 49ers players who have been ruled out of Thursday's contest. Dorsey is still in the process of rehabbing a biceps tear he suffered in August.
