Yeah, so that happened last night.

Apparently, becoming a double champ is possible – as Conor McGregor showed us when he knocked out 145-pound king Jose Aldo and wrecked 155-pound boss Eddie Alvarez. But keeping both belts is still the stuff of dreams, especially when the UFC has contenders in two weight classes clamoring for a title fight and threatening to quit the business if they don’t get it.

Here’s the UFC’s official statement:

UFC announced on Saturday that world lightweight champion Conor McGregor has vacated his featherweight title and opted to keep the 155-pound title he won by defeating Eddie Alvarez at UFC 205 on Nov. 12.

Interim featherweight titleholder Jose Aldo has now been elevated to undisputed champion, and following these developments, the interim UFC featherweight title will be on the line on Saturday, Dec. 10, as Max Holloway and Anthony Pettis battle for championship gold in the new main event of UFC 206.

The winner of the five-round bout, which will be held at Air Canada Centre in Toronto, will face Aldo in 2017 for the unified belt.

Oh well. It was fun while it lasted.
