Today the Role of DMX Will be Played by Coolio

DMX couldn't come to terms with the people putting on a celeb boxing match next month -- meaning they wouldn't fix it so he would win -- so X is out and Coolio is in.

Thunder Productions tells TMZ they have signed Coolio to the upcoming celebrity boxing match scheduled to take place in Alabama next month. They tell us Coolio has been much easier to deal with and "he is going to take this seriously."

X had previously agreed to the bout, but only on the condition he was guaranteed to win.
