Back rower Fyn Brown makes the switch to Castle Park from Dillingham Park ahead of the 2022/23 season having joined Championship opposition Ampthill from dismantled Premiership side, Wasps.
Fyn signed for former Premiership outfit Wasps straight from school, making his debut for the storied side at just 18 when he came off the bench against Leicester Tigers.
To facilitate more game time, the youngster was put on loan to Birmingham Moseley in his first year at Wasps before returning to his home club to compete in the Premiership Cup campaign.
Following the well-covered issues which saw Wasps cease to be, Fyn signed for Ampthill in November 2022, going on to make 18 appearances in the Championship for the side.
The young forward is looking forward to making the most of the Doncaster environment to help inspire further development of his skills.
