Former WCW and WWE World Heavyweight Champion Bill Goldberg has mentioned in the past that he wanted to do kickboxing for the Glory promotion in 2015.
However, according to the Wrestling Observer, his deal with the promotion fell through as of a few weeks ago and will not be fighting for them.
The reason why the deal never happened is because the promotion wanted to do the fight on May 8th in San Diego, but it was way too soon for him to get in shape to fight and to promote such a fight.
