CM Punk's first fight in the UFC has been announced and he will be taking on Mickey Gall at UFC 203 later this year.
One WWE star who won't be supporting his former colleague is Ryback, who as you may well remember had a rather personal feud with Punk following the wrestler turned fighter's comments after his WWE exit.
Ryback hasn't forgotten about that and today took a shot at Punk, via social media.

The Big Guy underwent surgery earlier this week on his nose to try and clear up a breathing problem he's been suffering with for a while.
He compared his post-surgery swollen and bruised face to what Punks will be looking like after his fight against Gall in September.
Ryback wrote: "Feeling like @CMPunk after his first fight, not the 16 mock ones he lost the first real one. #BeatUpJohnCena"
After Punk's departure from the WWE, he went on Colt Cabana's Art of Wrestling podcast and absolutely demolished Ryback, calling him an unsafe worker who didn't know how to wrestle at all and was a complete idiot.
He also said that Ryback purposely hurt him, causing him to get a concussion after managing to miss a table he was trying to throw Punk through.
That absolutely destroyed Ryback's perception in the public and The Big Guy still hasn't forgiven him.
