Washington bottled up Frank Gore (13 carries, 31 yards), essentially daring Kaepernick to throw the ball, and the QB responded by showing some veteran-like chemistry with veteran Anquan Boldin.
Boldin finished with five catches for 94 yards and two touchdowns a 19-yard grab at the pylon in the first quarter and a 6-yard, wide-open-in-the-end-zone reception in the third.
Vernon Davis also had a touchdown catch for the 49ers (7-4), who are tied for second with the Arizona Cardinals in the NFC West and are three games back of the Seattle Seahawks with five to play.
A loss would've put the defending NFC champions in trouble in their quest to return to the playoffs, but they're nowhere as bad off as Washington (3-8), which has dropped three straight and sits alone in last place in the NFC East.
Around the league
Packers • Coach Mike McCarthy says the chances of quarterback Aaron Rodgers playing Thursday at Detroit are "slim to none." McCarthy said Monday he isn't sure whether he will go with Matt Flynn, who rallied the team from a 16-point deficit to a 26-26 tie with Minnesota, or Scott Tolzien, who started the past two games but was benched in the third quarter Sunday. Rodgers has not played since he broke his left collarbone Nov. 4 against Chicago.
Browns • With quarterback Jason Campbell being treated for a concussion, Brandon Weeden will likely start this week against Jacksonville. Campbell was hurt in Sunday's 27-11 loss to Pittsburgh.
