Women's FAI Cup
A place in the Women's FAI Cup final is up for grabs this afternoon with Bohemians taking on Treaty United.

Athletics
Both Sarah Healy and Sophie O’Sullivan won their way through the heats of the 1,500 metres at the World Athletics Championships in Tokyo.
In the first evening session inside a packed-out National Stadium, together they also lifted the Irish mood, after the mixed relay quartet were unable to advance from their heat in Saturday’s morning session.
Sharlene Mawdsley said "mistakes" cost the Irish mixed relay team a place in the final.
The team of Mawdsley, Jack Raftery, Sophie Becker and Conor Kelly were sixth in their heat and failed to progress in Tokyo.
