Leitrim forward Philly McGuinness (26) suffered the serious injury playing for Mohill against Melvin Gaels in a club league match at Annaduff.
A statement from Leitrim GAA yesterday said that their thoughts were with the player and his family.
“Due to an injury sustained in a match Phillip McGuinness remains critically ill. Our thoughts and prayers are with him,” read the statement.
An engineer who works in Mayo, Philly made his Leitrim senior debut in 2003 and has been regular ever since, usually at wing-forward or midfield.
He comes from a family steeped in GAA history with older brothers John and Michael having played for Leitrim for many seasons up to recent years.
Their late father, Michael McGuinness, who was a teacher in Drumshanbo, was also a former county footballer and was selected at full-forward on the Leitrim Team of the Millennium.
Philly McGuinness emerged as underage player with Leitrim in 1999 and made an impression for club, Mohill.
He suffered the injury in the course of Saturday’s league game when he apparently received a heavy knock to the head. He was rushed to Sligo General Hospital and from there was taken to Beaumont in Dublin where his condition was described as serious.
