Colm Boyle (Mayo)

The ever industrious Boyle delivered a typically wholehearted display for James Horan's team, and drove forward to land an inspirational second half point.
Michael Murphy (Donegal)
Five time Ulster Championship winning captain, Michael Murphy, was at his brilliant best for Donegal against Kerry.
The Glenswilly clubman converted a last gasp free to secure a draw for Donegal on an afternoon in which Murphy registered 1-7.
Mattie Donnelly (Tyrone)
Mattie Donnelly was influential as Tyrone overcame a shaky start to defeat Cork at Croke Park.
Donnelly contributed three points and his switch into a more attacking position in the second half was pivotal.
