It would appear Saturday Morning Slam is done for the time being, as the show's no longer listed by WWE as an active show and the new television season has begun.
The Wrestling Observer Newsletter reports there were a breakdown of negotiations between CW and WWE executives. The network wanted to move away from taped matches and do more of a news magazine style format. Talks from both sides fell off and haven't been revisited.
There is no information on if WWE plans to try to shop the show elsewhere in the future.
