Sio Moore and Khalil Mack were so excited about the Oakland Raiders being on the verge of their first victory of the season that they forgot the game was still going on. That's the only explanation for this prolonged celebration that forced Oakland to call a timeout before getting hit with an offsides penalty late in the fourth quarter in its win over the Chiefs.
Granted, this is Week 12 and the Raiders are finally getting off the schneid. It's been a while, so we can't really blame them. Still, classic Raiders.
