Welsh hooker Kirby Myhill played in Major League Rugby between 2024-2026. He represented the Miami Sharks (2024-2025) and Old Glory DC (2026).

Born in Burry Port in Wales, Myhill attended the University of Wales Trinity Saint David in Lampeter. In his youth he played with his local club, Burry Port RFC, before entering the Scarlets system and playing with their U18 side. At senior level he represented Llanelli RFC in the Welsh premier division, as well as the Scarlets in the Pro14 (now the URC) over 60 times between 2010-2016. He then moved to Cardiff RFC between 2017-2023, earning just shy of 100 Pro14/URC caps between 2017-2023.

Myhill played with the Wales U16 & U20 sides, and is a fully capped Welsh international, earning his debut in October 2021 against the All Blacks as #1,172.

The Miami Sharks released a ‘soft’ announcement of Myhill’s signing on 13th October 2023, along with the signing of fellow welshman Rob Evans. He joined from Cardiff RFC in the United Rugby Championship (URC). Myhill ran for over 200m gained and completed 34 tackles in his 7 games (6 starts) during the Sharks’ respectable MLR season. On November 18th, 2024, the Miami Sharks announced the return of Kirby Myhill for his 2nd season with the team in 2025. In his 2nd season with the Sharks, Myhill recorded over 100 tackles made in 15 games (10 starts), scoring 4 tries on over 100m gained, including a try in the Sharks’ first (and only) postseason appearance in the Eastern Conference Semifinal against the New England Free Jacks.

Following the withdrawal of the Miami Sharks from MLR during the 2025/26 offseason, Kirby Myhill became a free agent and on 20th January, 2026, Old Glory DC announced that they had added the Welsh international to their roster for the 2026 MLR season.
