Colin Kaepernick had a rough start to the Thursday Night Football game in Week 7, and so did a waterboy on San Francisco’s sideline after an errant pass from the quarterback hit him right in the back of the head.

Here is a video of the throw and resulting body swerve after the high-powered throw jolted his noggin.

Seattle took an early 7-0 lead on a Marshawn Lynch goal-line dive. Kaepernick is going to need to improve on his accuracy if he has any hope of leading the 49ers to victory.
