Tight end Vernon Davis, who leads the 49ers with four touchdown catches, was a late addition to the team's injury report with a back injury. That injury did not keep Davis from practicing Friday -- he was a full participant -- and he is listed as probable on the team's injury report.
Three 49ers are listed as questionable for Sunday's game against the Jets: running back Brandon Jacobs (knee), receiver Ted Ginn (ankle) and nose tackle Isaac Sopoaga (ankle, knee). Sopoaga did not practice this week, and Ricky Jean Francois is expected to take his place Sunday.
Linebacker Patrick Willis (ankle) and punter Andy Lee (hand) practiced all week, and both are listed as probable.
