A decision will be made tomorrow night on whether Derry have been successful in their appeal against the outcome of last Sunday's All-Ireland minor football semi-final. The GAA's Games Administration Committee have called another meeting for Croke Park to determine if Cork's victory should be made void after one of their players received two yellow cards and yet was not sent off.

The content of referee Gerry Kinneavy's report remains undisclosed, and it will be crucial for Derry's request to be accepted that he admits an error. If this happens, it appears likely that the game will be replayed, in line with the result of Offaly's appeal following the 1998 All-Ireland hurling semi-final against Clare which was blown up early. Otherwise, it will be up to the GAC to make the decision - and so far this year they have backed the referee's decision.

The player in question, midfielder Kieran Murphy, was first booked after 11 minutes and again six minutes before the end.

Sean McCague, the president of the GAA, yesterday opened the Liam McCarthy exhibition at the association's museum in Croke Park. The exhibit commemorates the memory of the man after whom the All-Ireland senior hurling championship trophy is named. The exhibition traces the life of McCarthy, who was born in London to Irish parents in 1851.

In 1920, McCarthy donated £50 for the purchase of a silver trophy, asking that it bear his name and be presented to the hurling champions. For the first time, the four trophies for which the hurling All-Ireland has been played for were presented. The Croke Cup, now the national league trophy, was the All-Ireland Cup in the late 19th century. The Great Southern and Western Railway trophy was the prize until 1920, before being replaced by the original McCarthy Cup. A new McCarthy Cup was commissioned in 1992.
