Daisuke Sekimoto
After his release from WWE, Lesser returned to the independent circuit, adopting the ring name "Simon Grimm". On July 23, 2017, Grimm won his first singles title when he defeated both Daisuke Sekimoto and Doug Williams for the vacant XWA Frontier Sports Championship in Colchester, England. Less than a week later, Lesser wrestled for Pro Wrestling Pride defeating Doug Williams and Ultimo Tiger. In September, Grimm teamed with Dasher Hatfield and Mark Angelosetti in Chikara's 2017 King of Trios tournament, where they made it to the quarterfinals, before losing to Pete Dunne, Trent Seven and Tyler Bate.
