Well, that was quick.
The promotion wasted no time in announcing the bout. "Sots" was just a few hours removed from his second round submission win over Joe Lauzon via superior jiu-jitsu.
That pushed his record to 14-2 and 6-0 in the UFC.
The merger with the WEC has created a few match-ups that are currently clogging up the lightweight title picture so, despite the grapplers best efforts, he won't be getting a title shot anytime soon.
But he will be running up against a German stick of dynamite that presents a whole world of problems.
Dennis Siver, he of spinning back kick fame, is coming off perhaps the only impressive performance of the entire UFC 122 main card. He thoroughly dominated the heavy-handed Andre Winner with a big left hand and a modified rear naked choke.
He had a bit of a home-field advantage in that fight as it was contested in Oberhausen, Germany. Now he'll have to travel to his opponents home country to take on the Australian jiu-jitsu specialist in Sotiropoulos.
UFC 127 is a suddenly stacked card with an unconfirmed main event of B.J. Penn vs. Jon Fitch. The "Prodigy" blitzed Matt Hughes in his return to the welterweight division and now he'll get the chance to do the same against 170-pound stalwart Fitch.
Another welterweight showdown is rumored for the card as notorious brawler Chris Lytle is set to take on the always in-your-face Carlos Condit. The event will also feature Michael Bisping potentially throwing hands with Jorge Rivera.
