Hours following news that Bobby Lashley is off Great American Bash (joining Mark Henry as main eventers missing the PPV for health reasons), Dave Meltzer at WrestlingObserver.com just posted the following:
The [ECW house] shows were canceled because Vince McMahon made the call early in the day that Big Show will replace Great Khali on Sunday, against The Undertaker, in the Punjabi Prison match. Khali also has a diseased liver and is expected to be taken off the road.
Of course we hope for the best with Bobby Lashley and Great Khali’s health, and hopefully these are two cases of medical testing from WWE’s Wellness Program doing its job. Wow.
