The 49ers are practicing and Kaepernick is not throwing. His odds of playing on Saturday are decreasing significantly.
The San Francisco 49ers are starting their joint practice with the Denver Broncos, and while Colin Kaepernick is dressed and in pads, he is not throwing the football with the other quarterbacks. The team is doing individual work initially, and Kaepernick is taking drop-backs at the same as other quarterbacks. However, while they are throwing the ball, Kaepernick is not. He has been dropping back and taking the mental rep.
This will mark the fifth event (four practices, one game) where Kaepernick has not been throwing with the other quarterbacks.
