Dublin hurling manager Anthony Daly will have to plan without Paul Ryan for the remainder of the 2012 Allianz Hurling League.
Ryan impressed in the first 14 minutes of Dublin's Division 1 defeat to Kilkenny on Sunday as he racked up 1-03 for the Metropolitans. However, he was forced off with a hamstring injury and he is not expected to be fit before the end of the league.
The loss off the Ballyboden St Enda's man is a huge blow to Dublin as he has been one of Daly's leading scorers this year and his absence could prove costly as the reigning champions struggle to preserve their Division One status.
Meanwhile, Kilkenny chiefs have apologised to Daly after he was confronted by a spectator at the end of Sunday's clash.
Daly was approached after a fan invaded the pitch as the teams made their way off following Kilkenny's 5-16 to 6-12 win.
"The Kilkenny County Board have apologised to Dublin for an incident involving one spectator at the end of the game," Kilkenny county secretary Ned Quinn said.
The GAA are likely to investigate the episode but Dublin chairman Andy Kettle insists they will not be taking the matter any further.
"An incident took place, a man came out onto the pitch from the stand and jumped on Anthony’s back and a few unparliamentary words were said to Anthony," Kettle confirmed.
"The Kilkenny County Board, through Ned Quinn, were quick to apologise, as was Brian Cody. Nobody likes to see these things. As far as we’re concerned, we won’t take it any further.
"If the Kilkenny County Board want to take further action, that is entirely up to them. Anthony didn’t want to make a big deal of it. His focus is entirely on Tipperary next Saturday."
