In the wake of requiring Jerry Lawler to withdraw from the 4/27 PMG "Clash of the Legends" match with Hulk Hogan, WWE pulled Shelton Benjamin, Charlie Haas and The Boogeyman from Friday's Memphis Wrestling event, as well.

As a general rule, WWE is now barring its wrestlers from appearing on events run by the promotion. It remains unclear whether Lawler, who is contracted as an announcer but not a wrestler, will be allowed to work with the promotion in the future.

According to WrestlingObserver.com, the decision to pull Lawler from the show was not due to plans for VH-1, a USA Network competitor, to air footage from the show on "Hogan Knows Best." Sources say the reason was WWE's refusal to have a WWE-contracted worker appear in a high-profile match with Hulk Hogan.

In fact, WWE officials plainly told Lawler that he could not appear on the show if Hogan was also booked for the event.
