Bellator 138 fight card adds Daniel Straus vs Henry Corrales to 'Unfinished Business' line up

The biggest card of the summer for Bellator MMA just got a bit bigger.

Former Featherweight champion Daniel Straus has been struggling a little of late, dropping two of his last three fights, including his title shot at Bellator 132 against Patricio Freire (detailed results here). He may need to put a few wins together to get another chance at the belt he used to hold, beginning with undefeated King of the Cage veteran Henry Corrales (12-0).

The promotion recently announced that Straus will fight Corrales on the Spike TV-televised main card at Bellator 138: "Unfinished Business," which will take place inside Scottrade Center in St Louis, Mo., on June 19, 2015.

For those not keeping score, that "Unfinished Business" is between main event participants Ken Shamrock and Kimbo Slice.

Corrales started his career with five straight submission victories and has fought a few names who have been in the big leagues, including Jerod Spoon (Bellator) and Seth Dikun (WEC), en route to his current undefeated professional record.
