The winner of Saturday’s UFC 98 headliner between Lyoto Machida and Rashad Evans, a bout won by Machida via second-round TKO, had been slated to coach opposite Jackson, setting up a fall title bout.

Now, according to reports, Evans will be the opposing coach on TUF 10, but, unlike prior seasons, the coaches will not square off following the season finale. Instead, as confirmed by Dana White immediately following UFC 98, Jackson will square off with Machida for the light heavyweight title. According to Machida’s official website, the matchup will take place in September in Las Vegas, likely at UFC 103. Though the location may be incorrect, with UFC 103 rumored for the UK and Yahoo! Sports reporting it could take place in Texas, the September date appears likely.

The Ultimate Fighter 10 will begin taping on June 1 before debuting on Spike TV on September 16 following UFC Fight Night 19.

The UFC is set to officially announce the coaches during an afternoon conference call with the media. UFC President Dana White is then set to make a “special announcement” at 11pm tonight on Spike TV, with the announcement of The Ultimate Fighter 10 coaches widely expected.
