From Fightful:
“We'd reported that many on the WWE roster were expecting the WWE Draft to take place after Clash at the Castle. However, that doesn't seem to be anywhere near a slam dunk anymore. It's more like a half-court lob with your eyes closed. We're told by WWE sourced that several WWE Raw talent were unbooked from the Smackdown episode that follows Clash at the Castle. Many stars had been told that the Draft was likely taking place that week, but if it is, a significant number of crossover talent were not involved.
USA Network sources have told talent that the Draft isn't happening in the immediate future, have outright stated to that after WrestleMania is a likelier landing spot. WWE had not officially announced the Draft, and hasn't given us a confirmation about any of the dates, and talent hasn't been given a heads up about anything happening in the coming weeks.
We'll keep digging for information as to when the Draft could take place, if at all.”
