2 UFC veterans may soon be headlining an Elite XC event. At least if Nick Diaz gets his way. Diaz recently called out Frank Shamrock in an entry on GracieFighter saying he thinks he would “whoop his ass”.
Diaz made his UFC debut with a win at UFC 44 and followed it up with an upset win over Robbie Lawler at UFC47 in which Diaz taunted and eventually KO’ing the heavy favorite. He was dealt his first UFC loss at the hands of Karo Parisyan although he rebounded quickly with wins over Drew Fickett and Koji Oishi. He then lost a trio of fights to Diego Sanchez, Joe Riggs, and Sean Sherk. Following the string of losses the UFC released him from his contract in the spring of 2006. Diaz returned to win 2 more UFC fights but ultimately opted to leave the UFC.
In his next fight Diaz posted the biggest win of his career over Takanori Gomi with a rare gogoplata. The win was short-lived after Diaz tested positive for marijuana and the result of the fight was changed to a no-contest.
Sharock is a UFC champion winning the UFC middleweight championship, which is now the light heavyweight title, with a submission win over Kevin Jackson. He successfully defended the title several times including his last UFC fight against Tito Ortiz before retiring from the sport, at least temporarily. He has had a falling out with the UFC and will likely never return to the octagon for a fight. He returned to MMA with a one-sided KO win over Cesar Gracie last fall before losing via DQ to Renzo Gracie earlier this year. Most recently Shamrock won the Strikeforce middleweight champion with a win over Phil Baroni.
With a continued win streak in Elite XC Diaz would likely be targeted by the UFC to rejoin the organization, especially since his brother Nate Diaz just won The Ultimate Fighter 5 finale.
The fight is currently in the process of being set up for a future Elite XC card although it may not happen until sometime next year due to Shamrock severly injuring his knee and expressed his own interest in a rematch with Renzo Gracie.
