NFL Media's James Palmer captured the San Francisco 49ers quarterback throwing passes during Saturday's pregame warmup.
Kaepernick's arm appears to be getting its strength back. The quarterback was spotted throwing a 55-yard pass and had some other throws with improved velocity. Yet the plan is for the Niners to sit Kap until the team's third preseason game. The pressure will then be on him to prove that he's a better option than Blaine Gabbert.
