According to San Francisco 49ers head coach Jim Harbaugh, offensive tackle Anthony Davis' status for Thursday night against the visiting Seattle Seahawks is still up in the air.

Harbaugh stated that Davis is still reporting concussion symptoms. Jonathan Martin may once again start in his place at right tackle.

Davis suffered a concussion during week 11's game against the New York Giants.

Bowman will not practice

Harbaugh also stated that linebacker NaVorro Bowman will continue to rehab this week and will not practice with the team.

Bowman is recovering from a torn ACL and MCL suffered in last season's NFC Championship game.
