Who attacked Eddie Edwards on IMPACT Wrestling last week?

Eddie Edwards will challenge Eric Young for the IMPACT Wrestling World Championship on Saturday at IMPACT Wrestling Victory Road. However, tonight, he was here to find out who attacked him last week.
Edwards said he knew for a fact that it was Eric Young. When he called Young out, he was interrupted by Sami Callihan. The Draw appeared on the stage, sitting in a chair. Edwards said he should've known it was Callihan, but the former IMPACT Wrestling World Champion denied it.

Callihan then revealed Edwards' attacker, and it was none other than the future IMPACT Wrestling Hall of Famer, Ken Shamrock. Callihan and Shamrock had teamed with one another throughout the summer, and it seems that they've developed a rather psychotic bond.
Shamrock attacked Edwards and trapped him in the Ankle Lock as Callihan gave his longtime rival the thumbs down.
Backstage, Eric Young said that he wouldn't be surprised if Eddie Edwards didn't show up at IMPACT Wrestling Victory Road. However, he knows Eddie would, and looked forward to dishing out some severe punishment. As far as Bound for Glory, he'll be putting Rich Swann down for good.
