Casual Friday meant go kart racing for the Raiders.
With apologies to Madison Bumgarner, at least they weren’t dirt biking.
Instead of holding one of their Organized Team Activity days, Raiders coach Jack Del Rio took the team to a Bay Area go kart facility — as shown by several social media posts Friday, most prominently by Derek Carr.
The quarterback put a video on Instagram that highlighted his first-place finish in at least one race.
“Coach, I just wanted to say: Thank you for letting me come here and win,” Carr said on-camera with a smiling Del Rio.
