He's part of one of the most successful provincial teams in Ireland, he's mucked out in the Green jersey 72 times and is a Grand Slam winner but now Seán Cronin is donating the jersey from his fiftieth international cap to raise money for an incredible cause.
Speaking to Dermot and Dave, Seán told us about the campaign he is running on GoFundMe to raise money for additional screening for Sudden Adult Death Syndrome.
By donating just €10 you could be in with a chance of winning some incredible prizes including Seán's jersey from his fiftieth cap, and a whole host of other prizes including a signed cap from Shane Lowry, Katie Taylor's gloves and so much more.
And of course, he gave the skinny on returning to rugby post-lockdown.
