The NFL fined Raiders receiver Johnny Holton $12,154 for unsportsmanlike conduct.
Holton gave Patriots cornerback Jonathan Jones an open-hand smack on the helmet after a Derek Carr incompletion to Holton in the fourth quarter. Holton slapped Jones in front of side judge Allen Baynes, who immediately threw his flag.
The Raiders overcame the 15-yard penalty with their only touchdown in the 33-8 loss.
Holton had no catches on two targets.
