San Francisco 49ers defensive tackle Justin Smith is listed as doubtful to play this Sunday against the Arizona Cardinals.
Smith has a partially torn triceps, an injury he sustained two weeks ago against the New England Patriots.
Smith told the Sacramento Bee on Friday that that will play if the 49ers have a playoff game next week. He will likely miss his second straight game this weekend.
Tight end Vernon Davis is listed as questionable with a concussion he sustained last Sunday against the Seattle Seahawks.
