In early 2006, he wrestled at the Amarillo, Texas, based indy-wrestling company West Texas Wrestling Legends ran by his brother Chris. He made several appearances for the company before going back into retirement in July 2006. On January 13, 2007, he resurfaced in WTWL and defeated the WTWL Champion Thunder to win the championship.[1] After the match, WTWL wrestlers "Hobo" Hank, Mike DiBiase, Dice Murdock, nephew "Radical" Ricky Romero III and Mark's brother Chris Romero came down to celebrate the win with the new champion. Romero explained that his return was for one night only and he later vacated the WTWL Championship.
