Dual player

Dual player or dual star is a term used in Irish English to describe someone who competes in multiple sports - for example in Victorian Ireland cricket and hurling. The term today in Gaelic games typically describes a male player who plays both Gaelic football and hurling or, if a female player, a player of ladies' Gaelic football and camogie. The player does not necessarily have to play at the same standard in both sports. The number of dual stars at county level has decreased recently due to the increasing demands placed upon the best players of both sports.

In 1990, Teddy McCarthy of Cork became the first player to win both a football and a hurling All-Ireland in the same year. This unique achievement remains intact as of 2015.

Ex-Taoiseach Jack Lynch won one football and five hurling All-Irelands with Cork during the 1940s. To this day he is the only player in history to have won All-Ireland senior medals in six consecutive years.

A few players have won All Star Awards in both codes. These include:

Ray Cummins has uniquely won an All Star Award in both hurling and Gaelic football in the same year, 1971.

Dual county is a similar term for counties that have teams that play at the same level in both football and hurling.
