UFC Champion Ronda Rousey posted a reaction videon on Instagram, watching this week's Monday Night Raw and seeing Seth Rollins turn on The Shield for the very first time.
Rousey is a well-known lover of pro wrestling, and has indicated numerous times that she would love to be involved in a WWE angle down the road. There were rumors that her and her "Four Horsewomen" stable of fighters could make an appearance at SummerSlam, but the timing was not right, according to a few reports. If she does make it to WWE, it is likely they will try and use her for WrestleMania 31 next year.
It would be interesting to see whether or not Rousey or her friends would be able to compete in any way, given the UFC's generally strict policy on their fighters not doing anything that could possibly injure them. Tom Lawler recently appeared at a Ring of Honor event alongside ROH Tag Team Champions reDRagon, but was not allowed to be involved in anything physical.
