Colm Cooper's worst fears have been realised with confirmation today that the knee injury he suffered on Saturday is a ruptured cruciate ligament.
The eight-time All Star will undergo surgery in due course and will miss the rest of the 2014 season as a result.
Cooper underwent a scan on his right knee, which he injured in Saturday's All-Ireland club semi-final defeat to Castlebar Mitchels, at the Santry Sports Clinic in Dublin on Monday.
In a statement released through their website, the Kerry County Board confirmed the worst. It read: "A scan in the Santry Sports Clinic today has revealed that Colm Cooper has ruptured his cruciate ligament. He will undergo surgery in due course."
"Kerry GAA wishes our Senior Football Captain a full and speedy recovery."
Cooper was injured in the process of scoring a point for Dr Crokes in the 16th minute of Saturday's game in Portlaoise. Cooper had just glided past a couple of Castlebar defenders and dinked the ball over the bar with his right foot, but as he was kicking the ball over the bar, he was felled by a challenge from Castlebar Mitchels defender Tom Cunniffe.
Cooper looked to be in considerable pain as he clutched his right knee and was treated immediately by the Dr Crokes physios. He seemed to know immediately that he could not continue in the game, and he was duly substituted a few minutes after receiving some treatment.
He watched the remainder of the game from the bench, and there were immediate fears that he had suffered a serious injury.
However, confirmation that he suffered a ruptured cruciate ligament in his right knee is a devastating blow for the player, his club and for Kerry's hopes for the 2014 season.
Moved to centre-forward by manager Éamonn Fitzmaurice last year, Cooper enjoyed one of his productive seasons in a Kerry jersey and duly won an eighth All Star for some superb performances.
Cooper's injury robs Kerry of their playmaker and talisman and is a particularly cruel blow in light of the recent retirement of Paul Galvin.
Since making his debut in 2002, the 30-year-old has not missed a single championship game for Kerry, making 75 starts and coming off the bench once.
