One of the many sub-stories to last night’s UFC 141 headliner between Alistair Overeem and Brock Lesnar involves the victorious Dutchman’s training practices leading up to the bout. As many may remember, Overeem originally landed at Xtreme Couture after parting ways with Golden Glory’s gym. While his mother’s health-related forced him to return to Holland, it now appears the hard-hitting Dutchman had already left the renowned Vegas camp in the days prior to his departure from the States due to some pressure from Lesnar’s camp.

“There were some issues with Alistair training at Xtreme Couture because Randy (Couture), after he fought Brock, trained with him and signed a disclosure with them,” said Xtreme Couture striking coach Gil Martinez in conversation with Fightline. “So even though Randy isn’t at the gym, Brock’s people made it an issue so Overeem ended up not finishing his training here.”

Couture and Lesnar locked horns in a 2008 title-fight seeing the powerful 34-year old capture his lone championship. Though no specifics were given beyond Martinez’s statement, the problem seemingly related to concern internal sources at Xtreme Couture might have shared inside information on Lesnar’s abilities.

In the end it apparently made little difference, as Lesnar never made a serious attempt at taking Overeem down and was finished off midway through the opening round of their bout. The loss resulted in the former WWE Superstar’s retirement from MMA after a 5-3 mark in the sport with two consecutive strike-based stoppages at the tail end including last night’s loss.
