Jason made numerous appearances for the World Wrestling Federation in 1992 and 1993 as an enhancement talent. He made his first appearance on the July 4, 1992 episode of WWF Superstars, losing to Rick Martel. He would go on to lose matches in singles and tag team competition throughout July and August against Ric Flair, The Nasty Boys, The Mountie, Skinner, The Beverly Brothers and The Berzerker.
He returned in the main event of the fourth episode of the WWF's flagship television show, Monday Night Raw, on February 1, 1993, where he lost to Lex Luger in Luger's WWF on-screen ring debut. He again appeared on the April 26 episode of Raw in a losing effort to Mr. Hughes. After another loss to Luger on the June 5 episode of Superstars, he made his last appearance on the June 30, 1993 episode of Wrestling Challenge, losing to Bam Bam Bigelow.
A few months after his last appearance in the WWF, Jason debuted in Extreme Championship Wrestling on September 18 at the promotion's first UltraClash event, where he and Ian Rotten lost a tag team match to The Public Enemy. He would wrestle one more match, a victory over The Canadian Wolfman, before leaving the promotion.
Nearly a year later, Jason returned to Extreme Championship Wrestling on August 13, 1994 and defeated Mikey Whipwreck for the World Television Championship at Hardcore Heaven. Jason would successfully retain the championship several times against the likes Whipwreck, Rockin' Rebel, Hack Meyers and former World Television Champion J.T. Smith. On November 4, Jason was unable to become a double champion as he and Dean Malenko lost to World Tag Team Champions Whipwreck and Cactus Jack in a title match. That same night, Jason lost the World Television Title to 2 Cold Scorpio. Jason would then reignite his feud with Whipwreck, with the two trading victories, before Jason began to manage The Eliminators. On November 3, 1995, Jason and Whipwreck ended their feud in a match for Whipwreck's World Heavyweight Championship, which Whipwreck retained. A few weeks later at November to Remember on November 18, Jason lost to Konnan in only 14 seconds with Taz as the special guest referee.
Jason returned to ECW on August 11, 1997, where he lost to Chris Chetti via disqualification. Soon after returning, Jason began feuding with The Blue Meanie over the next few months, but never managed to pick up a win over Meanie. After their feud, Jason began to team with Justin Credible and he renewed his feud with Mikey Whipwreck as he and Credible wrestled against Whipwreck and Tommy Dreamer, but were unable to win any matches. Soon afterwards, Jason began to manage the Impact Players, Credible's new tag team with Lance Storm. On July 3, Jason and Credible finally won their first match together as they defeated Jerry Lynn and Prodigy. On August 29, Jason and Credible lost their final match together as they lost to The Sandman in a two-on-one Singapore cane match. Jason left ECW shortly afterwards before returning for one final match on August 2, 1999, which he lost to Jazz at Heat Wave.
On June 12, 2005, Jason appeared at the World Wrestling Entertainment-produced ECW One Night Stand pay-per-view.
