Manager Jason Ryan was informed of their intentions following the heavy 19 point defeat to Dublin at headquarters on Sunday.

The Lilywhites, who have struggled this season, introduced Hyland as a first half substitute against the ‘Dubs’. Mulhall did not appear during the game.

Both players are expected to head to America for the remainder of the summer which has been a thorny issue for the association in recent times.

The departures from the panel are a blow to Kildare who have lost a number of high profile leaders including Johnny Doyle and Dermot Earley in recent seasons

Ryan, who is a highly regarded manager must lift his players for a tricky away trip against Offaly in the qualifiers at Tullamore this Saturday.
