At Under Siege, Sami Callihan made his jaw-dropping return to IMPACT Wrestling as he targeted the man who broke his leg and took him out of action last year, Moose. The “Death Machine” vowed to make Moose’s life a living hell, playing mind games with the former IMPACT World Champion at every turn. Callihan even played a role in costing Moose a coveted IMPACT World Title opportunity in the Gauntlet for the Gold. Following a violent brawl on IMPACT! that saw Callihan lock Moose inside of a dark storage room, we can now confirm that a blockbuster match has been made official. Sami Callihan will collide with Moose in a match with no disqualifications, no countouts and no shortage of weapons – this is Monster’s Ball! What will happen when two of the most accomplished stars in IMPACT Wrestling go head-to-head? Find out at IMPACT’s biggest event of the summer, Slammiversary.
