Although Georges St. Pierre defending his welterweight championship against Nick Diaz is the featured attraction at tonight's (Sat., March 16, 2013) UFC 158 showcase at the Bell Centre in Montreal, Quebec, Canada, the co-main event of the evening is nearly as significant.

That's because Johny Hendricks and Carlos Condit will duke it out for the right to fight the winner of St. Pierre vs. Diaz later on this year.

Both men have been quiet leading into their 170-pound showdown, both because that's just the type of killers they are and because Diaz has been such a lightning rod for controversy during the build to this event. Perhaps that's a good thing, as there have been few distractions on the path to the Octagon.

Let's save the good stuff for when they're in the cage and gloved up, mmkay?

MMAmania.com will provide LIVE round-by-round, blow-by-blow coverage of the main card action on fight night (Sat., March 16, 2013), which is slated to air at 10 p.m. ET on pay-per-view.
