WWE is teasing that Paul Heyman will be on RAW tonight. He would be there to respond to Triple H laying him out last week.
Heyman is currently in as a regular in order to help build the SummerSlam bout between Brock Lesnar and Triple H on behalf of Lesnar. This is being done so that WWE doesn't have to use dates on Lesnar's contract.
Heyman's current deal with WWE runs through the SummerSlam PPV, but there is always the chance that both sides could agree to extend the deal.
