Joe Taimanglo submits Darrion Caldwell with a guillotine choke

— -- Darrion Caldwell is still a good bet to hold the Bellator MMA bantamweight championship some day -- but it won't be as soon as some thought.

Widely considered one of the top prospects in the entire sport, Caldwell (9-1) suffered a stunning defeat to Joe Taimanglo (23-6-1) on Friday. After dominating the first two rounds, Caldwell tapped to a Taimanglo guillotine just nine seconds into the third. The 135-pound fight headlined Bellator 159 at Kansas Star Arena in Mulvane, Kansas.
