Brennan captained the French U18 side when they took on their Irish counterparts in the first game of the second annual Six Nations Festival in 2019.
Son of Leinster and Toulouse legend Trevor and brother to Montpellier's tighthead prop Daniel, Brennan played his club rugby, like his ex-Irish international father, at Toulouse.
January 2020 saw him being included in the France U20 squad for their opening Six Nations ties against England and Italy.
