He is a two-time WWE Champion and a TNA legend. When it comes to in-ring skills, there's hardly anyone in the promotion who would be able to match AJ Styles.During a recent interview with ABENA, Styles revealed that he plans to retire in 2026 and that WWE's upcoming shows in Japan will likely be his last.“Very excited. I honestly thought I may not be here in the WWE, so to get the opportunity to come back is really awesome. It’s probably my last time as a performer going back to Japan, so I’m really excited to get back. “That means I’m gonna hang them up. I’m not gonna wrestle anymore. I’m gonna… soon, I’ll retire and I don’t think we’ll get back to Japan before I retire. I think this might be my last go in Japan as a performer," he said.So, it will be John Cena and AJ Styles both appearing in their final Crown Jewel event this year.#1 Roman ReignsThe Tribal Chief might also be appearing in his last Crown Jewel event in WWE. He has also spoken about calling it quits soon. During an interview with Vanity Fair, he mentioned that he might wrestle a year or two after his current contract expires, which is after WrestleMania 42."After I finish the contract that I’m in, we probably got another year or two max," he said.Roman Reigns makes fewer appearances in the company now. Since losing his Undisputed Championship to Cody Rhodes at WrestleMania 40, The OTC has largely remained on the sidelines, competing at major events only. He also remains busy with his filming schedule, and this is likely why he might hang up his boots soon.At this year's Crown Jewel, Roman will compete against Bronson Reed in an Australian Street Fight match. He has already beaten the 330-pound monster in the past at Clash in Paris PLE. This will be the second time that he goes one-on-one with the former NXT Champion.
