Colin Kaepernick

Well, the big show is finally here. After backing up Blaine Gabbert for five weeks, Colin Kaepernick was renamed the starting quarterback of the 49ers on Tuesday. The 28-year-old, who initiated a sports-wide movement to protest during the national anthem back in the preseason, grabs the reins as San Francisco travels to Buffalo this Sunday.

Social media reacted quickly to this mid-day Tuesday news:

If all goes well for Kaepernick, he'll be taking a knee at the beginning and end of the game Sunday (sorry, we tried to warn you).
