Hot-on-the-heels of the arrival of his international team-mate Juan Martin Gonzalez Samso, Cinti Luna also put pen to paper with the Exiles, in doing so becoming the fourth Argentine in the Irish squad.
The winger had four international caps to his name when he signed for the Club in November 2021, having made his debut in the 2020 Tri Nations Series last October.
Able to play across the three quarter line and also as full-back, Cinti made a total of 15 appearances for London Irish in his maiden outing in west London.
He scored three tries in the 2021/22 season, each in home wins over Worcester Warriors in the Gallagher Premiership, and in the Premiership Rugby Cup against London rivals Harlequins and also Leicester Tigers.
Cinti, alongside Exiles Agustín Creevy, Juan Martín González and Facundo Gigena, was called in to Michael Cheika's Argentina squad to host Scotland in the July international tests.
