49ers' Colin Kaepernick on track to make preseason debut (Yahoo Sports)

After being kept from throwing during team drills since Aug. 10 while nursing a sore shoulder, 49ers quarterback Colin Kaepernick threw against the defense on Monday. Kaepernick is on track to make his preseason debut Friday against the Packers in San Francisco's third preseason game. ''You know you got to get used to that cannon, man,'' 49ers receiver Bruce Ellington said.
