Tighthead prop Leon Brown burst onto the scene in 2012 when he played his first match for the Dragons Under-16s age grade side, after coming on as a replacement against the Ospreys. The Newport-born front row found his feet and became a regular starter for the Under-16s before moving onto the Under-18s and his high school team.

Brown made many appearances for Premiership side Cross Keys, appearing in the semi-final of the competition against Ebbw Vale at Eugene Cross Park. He made his debut for Dragons in 2016 against Leicester Tigers, coming off the bench in the Anglo-Welsh Cup. Brown has gone on to make 67 apperances for his home region scoreing five tries by the end of the 2022/2023 season.

Brown won Wales Under-20s honours before making the step up to the full senior side in the 2017 autumn international against Australia. The prop has gone on to earn 23 caps for his country making his most recent outing in the 2023 Six Nations Championship.
