The player whose status is most in doubt is defensive lineman Arthur Jones, who hasn't practiced all week after suffering a concussion last Sunday. Jones leads all Ravens defensive linemen in tackles (52) and sacks (four).
If Jones can't play, the Ravens would either start Terrence Cody or DeAngelo Tyson, both of whom have combined for one start this season. Jones has yet to be cleared but he is going through the concussion protocol and was scheduled to undergo more tests Friday afternoon, according to coach John Harbaugh.
The other starters who are listed as questionable are running back Ray Rice (thigh), Elvis Dumervil (ankle), center Gino Gradkowski (knee) and wide receiver Torrey Smith (thigh). All were limited in Friday's practice.
Here is the complete injury report:
Doubtful: CB Asa Jackson (thigh, did not practice).
Questionable: LB Elvis Dumervil (ankle, limited participation), C Gino Gradkowski (ankle, limited), DT Arthur Jones (concussion, did not practice), RB Ray Rice (thigh, limited) and WR Torrey Smith (thigh, limited).
Probable: Albert McClellan (neck, full participation).
