Shannon Eastin is in the starting lineup, set to become the first female official in an NFL regular-season game.
The 42-year-old has been assigned to work the Rams-Lions game Sunday in Detroit, where she will be the line judge.
Of course, this historic moment comes courtesy of a labor disagreement between the regular officials and the NFL, which is using replacements to start the season, Eastin among them.
Eastin, who has 16 years of experience, including most recently with the Mid-Eastern Athletic Conference, worked NFL exhibition games this summer, making her debut during the Packers-Chargers preseason game.
NFL and MEAC representatives didn't want to comment on her abilities, but plenty of other people have, although NFL Commissioner Roger Goodell did weigh in on the subject when it was first announced she would be a replacement.
