After much speculation, it appears the rematch between Dan Henderson and newly-crowned middleweight champion Michael Bisping is a go.

Bisping today said on his Sirius XM radio show the two men would step into the octagon to face off Oct. 8 in Manchester. The card is assumed to be UFC 204. The UFC has not confirmed the matchup or a venue for the proposed event.

“I’m announcing it,” Bisping said on his show. “First place ever … Dan Henderson vs. Michael Bisping for the 185-pound middleweight title. October 8 in Manchester. Live on pay-per-view. Do not miss it.”

The bout has appeared to have the promotion’s seal of approval since UFC President Dana White said Henderson would be the first challenger to Bisping’s title on the UFC 200 post-fight show.

Henderson scored a knockout for the ages when the two first met at UFC 100, but both men have seen their careers head in drastically different directions since then.

Bisping (29-7 MMA, 19-7 UFC) stepped up on short notice to face Luke Rockhold at UFC 199 and stunned the world with a knockout victory in the first round to become champion. The victory capped a four-fight winning streak that also saw Bisping score a victory over UFC legend Anderson Silva.

One has to look back to UFC 139 in November 2011 for the fourth most recent victory for Henderson (32-14 MMA, 9-8 UFC). Since 2013, Henderson has a 3-6 record, but his upset knockout of Hector Lombard on the same card where Bisping became champion has set up a potentially lucrative rematch.

Henderson recently suggested he is ready to retire “win or lose” against Bisping, so this bout could represent his final opportunity to wear UFC gold.
