SANTA CLARA, Calif. -- After an impressive quarter of action in San Francisco's preseason opener last week, Colin Kaepernick has grabbed a clear lead in the three-way competition to be the 49ers' No. 2 quarterback behind starter Alex Smith.
Coach Jim Harbaugh said Tuesday that Kaepernick has put some space between himself and young veterans Scott Tolzien and Josh Johnson.
Kaepernick moved the offence with his arm and his feet while guiding the 49ers to 10 second-quarter points in their 17-6 victory over the Minnesota Vikings. The second-year player was the game's leading rusher with 92 yards on three carries, including a 78-yard touchdown run.
He also completed passes to four different receivers, including a 15-yard sideline strike to rookie A.J. Jenkins to set up a field goal for San Francisco's final points.
