Minnesota Vikings safety Harrison Smith was ejected in the second quarter of Sunday's against the Tennessee Titans for pushing a referee.
After Vikings cornerback Antoine Winfield intercepted a pass by Titans quarterback Matt Hasselbeck, Smith pushed Tennessee wide receiver Nate Washington.
An official attempted to pull Smith away from Washington, but Smith pushed the referee away.
NFL Commissioner Roger Goodell attended the game, and Smith could be fined for the incident.
"He grabbed the official when the official was trying to separate them and pushed the official to the side," referee Jeff Triplette said afterward, according to the Minneapolis Star Tribune. "That's an automatic ejection."
Smith later apologized, according to Tom Pelissero of ESPN1500.com.
"I've lost my head before," Smith said, "but I've never had an incident with an official. I completely apologize for that. Right after I moved the ref, I realized it was a ref, and I realized that that was stupid and I should never do that. Stupid by me. I should never put the officials in a position like that. I should never touch them. I know that."
