ANOTHER quartet of Irishmen will head to Australia for a fortnight in April in the hope of realising their goal of becoming AFL footballers.

Oisin Mullin and Frank Irwin, who both hail from County Mayo, Fermanagh's Ultan Kelm and Clare product Cillian Rouine scored invites after impressing at the AFL Europe Combine in December.

They are all defenders in the Gaelic game, with Mullin and Kelm senior regulars for their counties and the other two progressing through underage ranks.

There's already been one standout performer from the Combine snapped up by an AFL club, with Lithuanian-born Deividas Uosis signing a two-year international rookie deal with Brisbane.

Mullin is considered the brightest prospect and cast in the same mould as the only Mayo player to ever reach the highest level in Australian Football – Pearce Hanley.

The 19-year-old finished second behind Uosis in the 20m sprint in a time of 2.86 seconds, was sixth in agility testing (8.06 seconds) and had the equal-highest standing vertical jump (70cm).

Irwin is the tallest (185cm) and youngest (17 years old) of this crop and has drawn some comparisons to countryman and Geelong's Mark O'Connor.

Kelm, 20, ran a slick 20m sprint time (2.87 seconds), while Rouine, 18, wasn't far behind (2.90 seconds) and performed solidly in most testing.

They will visit and train with select AFL clubs, including Geelong, Richmond and Essendon, and have previously trained alongside AFL Academy members.

Two of the four invitees from last year, Ross McQuillan (Essendon) and Luke Towey (Gold Coast), received AFL contracts for this season.
