Rousey has nabbed a guest appearance in Episode 20 of the show's second season, scheduled to air this spring. She'll play a female prison inmate named Devon Penberthy. Devon is from a blue-collar family in New Hampshire and is behind bars for transporting weapons across state lines. She is, according to a description from NBC, a "tough, athletic woman who knows how to fight and handle a weapon."
Sounds like just the type of person who could go toe to toe with Jane (Jaimie Alexander) and the rest of our heroes; however, it's unclear at this point whether Rousey's character will be a friend or foe to the FBI.
This isn't Rousey's first foray into acting. She previously guest-starred on Entourage and had small roles in The Expendables 3and Furious 7. She also hosted an episode of Saturday Night Livelast year.
Blindspot airs Wednesdays at 8/7c on NBC.
