Joe Canning is to undergo surgery on an injured groin and will miss the entirety of the Leinster championship, Galway GAA confirmed in a statement this afternoon.
The Portumna player was stretchered off in the closing minutes of Galway's league semi-final defeat to Waterford, following a collision with Kevin Moran.
In their statement, Galway confirm that Canning will be out for between 14 and 16 weeks, meaning he will only be back available in mid-July.
Galway will also have to plan without St Thomas's Fintan Burke, Galway's U21 captain last year, who damaged his cruciate ligament in the All-Ireland club final defeat to Ballyhale Shamrocks.
Micheál Donoghue praised the duo in the statement and wished both players a speedy recovery.
"I, and all the team wish Joe and Fintan a speedy recovery from their injuries. They were both very unlucky to pick up injuries at this stage in the season."
"Even by his own high standards, Joe Canning’s performances this year have been exceptional. He is in good spirits and has a positive mindset facing surgery and rehab period."
"Fintan Burke is an exceptional young talent and his injury is a difficult blow in what was shaping up to be a great season for him. He was outstanding in St.Thomas' run to the All-Ireland Hurling Club Final and is determined to get back playing for his club and Galway.
"I, our medical and support team will be working with Joe and Fintan closely to help with their recoveries and return to the squad."
