Rousey joined the 9-1-1 in its third season, and she made headlines when she almost lost her finger during filming.

As Rousey's co-star Ryan Guzman told Us Magazine, "Ronda pretty much chopped half her finger off. She’s a true badass in every way she can be. Literally, she was in the middle of a take and she didn’t want to ruin the take, so she kept on going and then after the end, she was like, 'Guys, I think something’s wrong with my finger.' Cut to, we actually see that her finger has pretty much fallen off."
