Just when the dust has settled on their feud, CM Punk and the WWE are at it again, this with WWE firing the first shots.
With the news of WWE's doctor, Chris Amann filing a lawsuit against Punk (Phil Brooks) and Colt Cabana (Scott Colton) for defamation, the WWE has wasted no time in compiling a video to contradict the the former WWE champion.
Titled simply 'WWE address CM Punk's allegations', the three minute silent video shows footage of several of Punk's matches in WWE - during the timeframe in which he claimed to have a staph infection the size of a tennis ball on his back.
The video zooms in on Punk's back, to show there are no noticeable lumps on him at that time and it's clear that the WWE are still harbouring some hurt feelings about the split.
Is the lawsuit all Amann or is it WWE backed?
The interesting thing about the lawsuit, and the subsequent video, is the timing of how everything has happened.

Punk's tell-nearly-all two-part interview with close friend, Cabana, was published on Cabana's podcast, Art Of Wrestling in November and it seems as if Amann (and the WWE) have been biding their time ever since.
For most people, Punk has moved onto the UFC, where he is training hard for his debut fight, which will hopefully be later this year, and the WWE is getting ready for Wrestlemania, so the timing is certainly odd.
Then there's the timely absence of the WWE's top Diva, AJ Lee, who is married to Punk. She hasn't been seen on WWE TV since December and recent rumours had suggested that she was being kept off TV for more than just an injury.
Will it stop Punk's UFC debut?
It appears as if those rumours were right and while Amann has his own legal team at the moment, the interesting thing to note will be whether the UFC get involved.
It's going to be the story to follow in the coming months and will likely drag on for a while, possibly jeopardising Punk's start to his UFC career.
Dana White and co. are already going through a mass shake-up with their drugs testing program, so the last thing they need is another headache, but if the WWE get involved and come after one of their star attractions, you have to think they'll level the playing field.
