History is about to be made this weekend in the NFL.
This weekend, Sarah Thomas will become the first woman to officiate an NFL playoff game between the Patriots and the Chargers.
Sarah is no stranger to the NFL either. The NFL hired her back in 2015. She was the league's first full-time female official and before that she was the first woman to officiate a major college football game.
She's the 'Down Judge,' which is just under the Head Referee and Umpire. Down judges manage the chains, set the line of scrimmage, mark the spot where the play ends, and make line-of-scrimmage calls like false starts and offsides.
