Jon Walters has pulled out of the Ireland squad for Friday’s friendly in the Aviva Stadium.

The FAI international Player of the Year has returned to Premier League club Stoke to get treatment on a hamstring injury.

Martin O’Neill’s men play Switzerland on Friday and Slovakia next Tuesday in the Euro 2016 warm-up matches.

Walters is set to be in attendance at the Switzerland game and may be back in contention for the second match.

Meanwhile, Manchester City’s Jack Byrne remains in training with the senior squad after being originally called up to the under 21 squad.

Byrne, 19, has impressed during his current loan at Dutch side SC Cambuur this season.

It is still expected that he will line out for the under 21 side in their European Qualifier away to Slovenia next Monday.
