Ronda Rousey is currently on a six month medical suspension in order to recover from the injuries she sustained in her recent match against Holy Holm, but once she's healed you can expect to see her take Holm on again.
UFC president Dana White says, "I think that if we didn’t make the rematch, me and [UFC CEO] Lorenzo [Fertitta] should probably lose our promoters’ license. Yeah, that fight’s going to happen. I don’t know when, but that’s the fight that will happen."
There's no doubt that Rousey will be back in fighting shape in no time and ready to take back her title.
