“I am definitely excited to have Ken Shamrock's nephew as a part of the Strikeforce team,” said Strikeforce CEO, Scott Coker. “Jeff possesses that incredible Shamrock strength that his family is known for. I expect great things from Jeff and look forward to his professional debut.”

"I am very thankful for this opportunity," said Jeff Shamrock who, at 18 years old, is the youngest member of Ken Shamrock's Lion's Den Reno Elite Fight team. “Signing with Strikeforce gives me a chance to put all of my training to the test, and to develop an elite fighter. I am really looking forward to fighting for them."

According to Ken Shamrock, "Jeff is a very strong and aggressive fighter. He has been training hard and has developed impressive skills on the mat, including his take down and submission skills. I have no doubt that Jeff will do extremely well."

Jeff Shamrock is expected to make his professional debut at the next Strikeforce event, fighting at 170 pounds. In his amateur debut in August, he defeated Kyle Davey by way of first round submission at Feather Falls Casino in Oroville, Calif.
