Maguire came through the ranks of Boyne RFC in Louth and went on to play underage rugby for Leinster at U18, U19, and U20 level, as well as representing the Ireland U18s and U19s.

In 2016, Maguire made a move to Old Wesley RFC, where he has played over the past four years, impressing in the AIL while also winning caps for Ireland Universities and Ireland Clubs.

He was a hooker during his youths rugby but moved to loosehead prop with Old Wesley due to strong competition with the likes of Ronan Kelleher and Tadgh McElroy at hooker within the Leinster system.

The change of positions has proven successful, with Maguire featuring for the Connacht A team in their 2019/20 Cara Cup campaign, while also enjoying a stint in Perth with the University of Western Australia last year.

Maguire was brought into the Leinster set-up last January as a member of their training squad and will now have the opportunity to face them as he looks to push on with the Dragons and earn a longer-term deal.
