I talked to Ishe after the show last night, and he said he thought Ahmed probably took one round. Like all fighters (but seemingly legitimately in this case) he felt he won pretty easily, and that his body shots were taking it out of Ahmed. (Tommy Gallagher said much the same on the official site).
Ishe said the atmosphere in the warehouse for that fight was tremendously electric, it being the first "grudge" match of the series. Apparently, Mark Burnett came to see him (and presumably Ahmed) in the dressing room before the fight, and said that he really appreciated, and was impressed by, the fact that they were taking this dangerous fight so early.

One other snippet he told me that I thought was pretty funny. Apparently, after every fight, Sly, Ray, and the celebs in the audience all retired to Sly's office for an after-party. The fighters found themselves looking longingly over in the direction of the office, just yards away, and wishing they could join in, and feeling like monkeys in a zoo as the party-goers looked out at the office windows at them.
