UFC in Winnipeg has another main casualty - Nogueira out

Antonio Rogerio Nogueira is being reported as out of the UFC's next PPV show, on 6/15 in Winnipeg, where was to be facing Mauricio "Shogun" Rua in the No. 2 match on the show.

It's been reported by Mike Chiapetta at http://www.mmafighting.com/2013/6/2/4389558/antonio-rogerio-nogueira-injured-out-of-ufc-161-ufc-hunting-for in a story first reported in Brazil by Globo.

Nogueira vs. Shogun was just underneath the Dan Henderson vs. Rashad Evans main event.  The original main event Renan Barao vs. Eddie Wineland for the interim bantamweight title, also fell out with an injury to Barao.

Who would you have the most interest in for Fabricio Werdum's next title defense?
