The GAA have confirmed that the hooter system will be used for the first time this weekend in the Sigerson cup.

The clock, which will count up from zero, will be operated by a timekeeper, who will only stop the clock when directed to do so by the referee.

The clock will only be stopped for relevant on-field injuries or other incidental delays not otherwise provided for in the playing rules.

The hooter system is due to be used in the Championship this summer.
