At the UFC on FX 3 post-fight press conference UFC president Dana White indicated that we are likely to see Junior Dos Santos vs. Cain Velasquez II at UFC 152. He also said that Joe Silva would be giving BJ Penn a call to confirm if he really wanted to take on Rory MacDonald. If everyone is happy then that fight is likely to be co-main event at UFC 152.

Here is what Dana said when asked about the Penn vs. MacDonald fight:

“Yea, we’re gonna do it. Joe is calling BJ and his crew tonight to make sure that was the case and then that fight is gonna happen.” Then when asked for a date White said “Toronto, it will happen on the Toronto card, it will probably be the co-main event.”

UFC 152 will take place on September 22nd at the Air Canada Centre in Toronto, Canada.

Junior Dos Santos (15-1) defeated Frank Mir recently at UFC 146 in May. The undefeated UFC heavyweight champ won via TKO in the second round after sucessfully avoiding Mir’s takedown attempts and most of his strikes.

Cain Velasquez (10-1) was also in action at UFC 146 where he made quick work of Antonio Silva. The former champ took the fight to the mat and went to work with his ground and pound earning and eventual stoppage in the first round.

BJ Penn (16-8-2) will come out of retirement to take on McDonald. The Hawaiian fighter was last in action against Nick Diaz at UFC 137. The fight against Diaz was an epic stand-up war with Penn losing the fight via decision which prompted his choice to retire from the sport.

Rising star Rory McDonald (14-1) will enter the fight coming off a victory over British fighter Che Mills at UFC 145 in Atlanta. Rory put on a dominant performance winning via TKO in the second round. MacDonald called out BJ Penn stating that he thinks it would be a good matchup on MMAFighting.com’s show The MMA Hour.
