Monaghan forward Jack McCarron has been ruled out for the rest of the year.
McCarron, who made four Allianz Division One appearances for the Ulster county in the spring, suffered a knee injury while on club duty with Carron last month.
Monaghan manager Seamus McEnaney has now confirmed that the 28-year-old attacker has now been ruled out until 2021, which means McCarron will miss the All-Ireland Championship later this year.
Monaghan are due to face Cavan in the preliminary round of the Ulster Championship on the last weekend in October.
“I’m very disappointed for him,” Monaghan manager Seamus McEnaney told the official GAA website.
“Through the National Football League early on in the spring before the lockdown he was going really well for us. He was going really well in the games he played in and he was going really well in training before the Kerry match.
“Genuinely I’m very disappointed for the lad. He puts in such a huge effort, he lives his life around football and football is his life. It is a setback, but as I said to him the morning after he got a bit of work done, his recovery starts now and we will get him ready for next spring.”
