Gotta catch 'em all. Or, in Michael "Venom" Page's case, gotta knock 'em all out.
The welterweight improved his pro record to 11-0 at Bellator 158 after delivering a vicious knee to the head of Evangelista "Cyborg" Santos.
To add insult to injury, Page then rolled a Poké Ball toward his downed opponent, in reference to the Pokémon Go craze sweeping the gaming world.
The flying knee seriously fractured Santos' skull. He was taken to a hospital in London and will have surgery in the United States. WARNING: The following image is very graphic. If you really want to see it, scroll further down the page.
His ex-wife, fighter Cris Cyborg, created a gofundme account to help the veteran fighter pay medical bills.
Commentator Joe Rogan says the injury is the worst he has ever seen in mixed martial arts.
Page jumped on Twitter to support Santos, sending the injured fighter best wishes and also linking to the fundraiser.
I would like to express my best wishes to @CYBORG121 & his family, as he is currently being held in hospital for a fractured skull

Page has one more fight left on his Bellator contract, and MMA fans have been wondering about a jump to UFC for quite some time.
Maybe he'll bring along some Poké Balls if he jumps ship.
