It is a situation which is rearing it's head a lot more these days - the connection between the WWE and UFC.
The lines have certainly become a lot more blurred lately with CM Punk moving to UFC after leaving WWE and Ronda Rousey appearing at WrestleMania XXXI.
Rollins vs UFC?
The issue was mostly raised in the week leading up to WrestleMania when rumours were strong that Brock Lesnar was set to jump ship from WWE to UFC.

Lesnar decided to sign a new contract with the wrestling promotion and commit his long term future to the squared circle instead of the octagon.
Following WrestleMania, Rousey has been in the rumours about an eventual WrestleMania match and the two have been closer than ever in recent months.

With Rousey fighting on Saturday night at UFC 190, fans took to social media to discuss their thoughts on it, and one fan started a war.
A UFC and WWE fan tweeted UFC President Dana White claiming that "Vince has you beat" by only charging $9.99 for the WWE Network whilst UFC is only available on PPV.
White responded with a tweet which received a backlash from angry fans.
Referring to the WWE as 'fake s***', White earned a lot of angry tweets from WWE fans who all fired back.
In multiple tweets after that, White claimed to have nothing but respect for the wrestlers but insisted on his point that it was fake.
It's not just fans who have responded to the tweet as countless wrestlers themselves have responded.
Former WWE superstar and current TNA wrestler Bully Ray demanded that White apologise for his comments, but arguably the best response goes to current WWE World Heavyweight Champion Seth Rollins.
A bit sarcastic from the self proclaimed future of the WWE but with just under 5000 retweets, its clearly a tweet which pleased wrestling fans.
Behind enemy lines?
The latest connection between UFC and WWE is a particularly bad one with White seemingly angering a lot of fans and superstars.
But it may already be too late for any UFC personalities to grace the WWE ring with White having claimed since WrestleMania that a match including Rousey is unlikely.
Who knows if we will ever see Rousey in the WWE again, but either way the recent exchange will just hype up any other appearances by her and of course, CM Punk's debut match in UFC.
