Jon Jones vs. Dan Henderson Headlines Submission Underground 2 Event on Dec. 11

Jon Jones and Dan Henderson never did fight at the doomed UFC 151 event, but they will square off in the headliner of Submission Underground’s second offering on Dec. 11.

Chael Sonnen, the event’s promoter, announced the matchup during "The MMA Hour” on Monday. Submission Underground 2 takes place at Roseland Theater in Portland, Ore., on Dec. 11. Jones vs. Henderson will be an eight-minute grappling match contested under Eddie Bravo Invitational rules, which is a submission-only format.

The announcement came shortly after USADA revealed that Jones would be suspended for one year for failing an out-of-competition drug test ahead of UFC 200 on June 16. Jones tested positive for clomiphene and letrozole, both of which are banned by USADA. While Jones’ attorney argued that the positive test was the result of a sexual enhancement pill, an independent panel still found Jones at fault. His suspension will run through July 6, 2017, but Sonnen doesn’t expect that the interim light heavyweight champion’s participation in Submission Underground will be an issue.

"I don't think that affects it," Sonne said on “The MMA Hour” “Grappling never has in the past, but the commission, if they ask for something, particularly if you're making a deal, you want to do it their way. So I imagine there could be some red tape there.

"I don't have a concern about it. But I suppose we have to go back to the other side and make sure there's nothing missing there.”

Jones was supposed to defend the light heavyweight title against Henderson at UFC 151 on Sept. 1, 2012. The event was canceled after Henderson withdrew from the bout due to injury and “Bones” balked at facing Sonnen on short notice. Henderson retired from MMA following a narrow loss to Michael Bisping in the UFC 204 headliner last month.

Sonnen also announced that Miesha Tate and Jessica Eye will meet in the Submission Underground 2 co-main event.
