A fight between Chael Sonnen and Lyoto Machida is all but a done deal.
Sources close to the situation tell Fighters Only that Sonnen will be making his UFC return at light-heavyweight and is almost certain to face the Brazilian former champion.
The fight is apparently being considered for UFC 136, which takes place on October 8th in Houston, Texas. No fights have been announced for that card but Jose Aldo and Kenny Florian are expected to headline.
