Utah native Sione Mahe played in Major League Rugby between 2023-2025. He represented the Utah Warriors for his entire MLR career.

Born in Provo and sharing the hometown of Herriman with the Utah Warriors, Mahe played with the Canyons during the 2022 Collegiate Rugby Shield, a Utah-based event to identify MLR prospects. The Warriors announced the signing of Sione Mahe shortly into the 2023 season, in March of that year but did appear in a regular MLR game for the Warriors. Following the 2023 season, the Utah Warriors announced the re-signing of SIone Mahe in early November, ahead of the 2024 MLR season where he earned his MLR debut for his hometown team, starting 2 of his 3 appearances and earning 90m gained in posession before suffering an ACL injury that ruled him out for much of the year.

On December 31st, 2024, the Utah Warriors announced the return of Sione Mahe for his 3rd season with the team in 2025.
