Seymour made a statement to the media after the game.
"I apologize to my teammates, coaching staff and the organization, also the Raider Nation. I'm disappointed that I wasn't there to finish the game with my teammates. I think that it’s an emotional game and I shouldn't have let my emotions get the best of me. No excuses."
The punch certainly wasn't full force, and it's debatable whether Seymour deserved to get ejected. The NFL most likely will review the incident this week.
