Rivers entered semi-retirement due to medical conditions near the end of Smash 4's lifespan; in an interview with ZeRo at Smash 'N' Splash 4, Rivers revealed that he suffers from tendonitis and thus doesn't enter many tournaments. More recently, Rivers has switched to the Switch Pro Controller for a more ergonomic control scheme and has begun to compete again in Ultimate.
He is currently affiliated with the DMG crew, and was formerly in OcS (Ocean County Smash).
On November 29th, 2018, Mentality Esports signed Rivers to prepare for Super Smash Bros. Ultimate. However, Mentality Esports shut down on March 17th, 2019, thus ending their sponsorship.
