Shawn Michaels on the Shelf 4-6 months

from Jason Powell at prowrestling.net:

Shawn Michaels suffered an injury at the WWE Raw tapings on Sunday night in St. Louis. He is believed to have suffered a torn triceps muscle, according to Mike Johnson of PWInsider.com. Michaels is slated to appear in an unsanctioned match against Chris Jericho at next Sunday’s Unforgiven pay-per-view.

Jasson Powell’s POV: This was be a huge blow to WWE and the Raw brand, which is already missing John Cena and Randy Orton. With Mr. Kennedy and Umaga out on the Smackdown side, the injuries are piling up for WWE.
