(Reuters) - New England Patriots head coach Bill Belichick has been fined $50,000 by the National Football League (NFL) for grabbing an official's arm at the end of Sunday's loss to the Baltimore Ravens, the league said on Wednesday.

Belichick's fine was formally for "impermissible physical contact with an official," the league said.

The Patriots coach, who has led New England to three Super Bowl championships, grabbed Esteban Garza's arm while exiting the field after a late field goal for the Ravens won the game.

"I was really looking for an explanation from the officials as to whether the play was under review and I did try to get the official's attention as he was coming off the field to ask that, but I really wasn't able to do that," Belichick said on Monday.

"I have never meant any disrespect or in any way tried to abuse or be disrespectful to the officials and the job that they do."
