Thomas, who was born in Pascagoula, Miss., has been a football referee for around two decades, having officiated her first varsity high school game in 1999.
Following this week's games, the remaining teams will go on to play the conference championships before the two remaining teams will meet at Super Bowl LIII at Mercedes-Benz Stadium in Atlanta, Georgia, on February 3, 2019.
The moves come on the heels of the of the National Basketball Association announcing that referees Ashley Moyer-Gleich and Natalie Sago would be promoted to full-time status back in November, becoming the fourth and fifth women in league history to reach that level.
Thomas says she wants to focus on "being the best official I can be". "Field presence is what they talk about", she said in an interview with SB Nation.
This will be a special moment for Thomas, a Brandon, Mississippi resident with three children, and a monumental postseason game for the entire NFL. "When we carry ourselves with confidence and walk into a room with confidence, the atmosphere changes".
