Town forward James Collins has missed out on the Ireland squad for the two UEFA Euro 2020 qualifiers next month.
The 28-year-old was top scorer at Kenilworth Road with 25 goals this term, earning a place in the provisional squad, but boss Mick McCarthy has opted to go for Scott Hogan from Aston Villa and Preston North End's Callum Robinson instead.
Collins, who has featured at both U19 and U21 level for his country, is yet to make his senior Ireland debut, as despite being in McCarthy's squad back in March, he was an unused substitute for the matches against Gibraltar and Georgia.
