So when the question was asked about whom he'd like to fight next, MacDonald had one guy on his radar.
"Carlos Condit," MacDonald told MMAjunkie.com Radio. "But he's busy right now. He's got a fight coming up, so I have to work my way up to that level (with someone else)."
Condit, of course, won the interim title in February with a victory over Nick Diaz. He's now on the sidelines awaiting a likely UFC 154 headliner with MacDonald's training partner: UFC welterweight champion Georges St-Pierre.
Additionally, the UFC recently slotted top contenders Johny Hendricks and Martin Kampmann for a co-headliner at UFC 154.
That left MacDonald with few options.
"But then the UFC approached me about the fight with B.J.," said MacDonald, who now fights Sept. 22 at Toronto's Air Canada Centre in a pay-per-view co-headliner. "It sparked my interest, so I figured, 'Why not?'"
Condit-MacDonald was the fight i wanted to see as well, likely will happen once GSP beats Condit.
