Ronda Rousey's back ... to acting!
The UFC legend scored herself a guest role on the hit NBC show "Blindspot" -- where she'll play a tough prison inmate who's serving time for transporting weapons across state lines.
No word on when the episode was shot -- but according to Damon Martin of FoxSports.com, the episode is expected to air in late March.
Ronda has not made an official decision on whether she'll fight again -- but most people think she's likely done after losing her last 2 fights.
This is a big deal for Ronda -- if she crushes the "Blindspot" gig, it could lead to bigger and better things outside the octogon.
