It looks like the WWE Draft has been pushed back.
Fightful previously reported that several Raw wrestlers were scheduled for the first Smackdown following Clash at the Castle on September 9, while SmackDown talent was slated to appear on the September 5th edition of Raw. This led to speculation the WWE Draft would be shortly following the Clash at the Castle PPV, scheduled for September 3rd.
However, Fightful Select reported today that the belief among the wrestlers is that those plans are no longer a slam dunk anymore. Several Raw stars have been unbooked from the SmackDown episode following Clash at the Castle.
