After the one-off appearance at the WWE produced ECW One Night Stand, Funk then returned to the independent circuit and made appearances in Japan. He claimed to be semi-retired after wrestling in his last match in September 2006 against Jerry "The King" Lawler in an Extreme Rules match at The Great Plains Coliseum in Lawton, Oklahoma for the promotion Impact Zone Wrestling. Funk was also the special guest referee during the Raven and Johnny Webb vs. Khan Kussion and Homeless Jimmy match at "Cold Day in Hell" on May 24.
