Well, in a "blink and you'll miss him" moment, it seems that WWE has decided to release Test from his contract. It is believed that his release had to do with him violating the Wellness Policy of the company.
Test was last used as cannon fodder for Bobby Lashley, and lost match after match against the current ECW Champion, which of course was the final punishment before being released from his contract.
