First MMA fighter on the Ring Magazine, fight in the Octagon

First MMA fighter on the Ring Magazine, is fighting inside the Octagon and is not even a boxer.  We do not know exactly what are the qualifications to be on the cover, but we certainly understand that you should be popular. Ronda Rousey has taken over MMA world and it looks  like she is doing the same thing in the boxing world. The Ring magazine is a boxing-centric magazine and while there are certainly a number of female boxers that could be featured they chose an MMA fighter instead.

Congrats to Ronda Rousey.

Should I tag this under MMA or boxing category?
