Dave Meltzer is reporting today that Shawn Michaels has a blown out knee. HBK missed last nights house show and is going to try to gut it out tomorrow night at Judgment Day.

This injury is considered serious. This is absolutely terrible news for WWE as there have been a ton of top name injuries as of late.
