A video from NASCAR's Nationwide series has gone viral - for all the wrong reasons.

Sports websites are buzzing over footage from this weekend's race in Montreal. The video is from the inside of driver Steve Wallace's car. Wallace had just been involved in a wreck that also included Patrick Carpentier, who was in his final race. As Wallace pulled up to Pit Road, Carpentier's crew chief, Jeremy Baxter, reached into Wallace's car and began pulling his hair before he was separated by other officials.

Tensions boil over all the time in NASCAR, but the situation was unique because it involved a crew chief actually reaching into another driver's vehicle.

Baxter later released a statement in which he apologized to Wallace for his actions.

"I'm sorry for what happened after the race on Saturday and I take responsibility for my own actions," Baxter said in the statement. "I called Steve today and apologized. I was just very frustrated and let my emotions get to me. That was Patrick's last race and we wanted to make it special. We really thought he had a shot for the win and everything boiled over when that chance went away in the wreck. Everyone was just racing hard and there was no intent to wreck anyone. There's no excuse for what I did after the race and I apologize to everyone."
