William Porterfield will not play for Ireland this week

Ireland will be without captain William Porterfield and Niall O'Brien for the forthcoming matches against Bangladesh 'A', New Zealand and Scotland.

Both are currently playing in the Twenty20 Cup and Gloucestershire take on Northamptonshire in a four-day game starting on Sunday.

Kyle McCallan has been named captain for all three games.

Trent Johnston will return to Ireland colours for the Twenty20 clash with Bangladesh at Eglinton on Friday.

Porterfield described his decision to play for Gloucestershire as "definitely the hardest decision I've ever had to make".

"I didn't think it would come so early in my time at Gloucester but I'm just embarking on my professional career and trying to cement my place in the team.

"An injury to Craig Spearman has given me an opportunity to stake a claim for a permanent position, and I have to take it. If I don't, somebody else will.

"I'm in possession at the moment, and I've been assured of my place in the team for the four-day game.

"I feel it's the right decision for me at this stage of my career."

Ireland coach Phil Simmons said Porterfield's decision was "obviously not ideal".

"I understand his situation as he tries to establish himself in the county game; he's a professional and that's his job.

"It's hard for us losing both Niall and William, but we have got good depth to the squad, and we are also boosted by the availability of Gary Wilson and Eoin Morgan."

Ireland play Bangladesh 'A' in a Twenty20 game at Eglinton on Friday and then face the same opposition in a 50-over game at Bangor on Sunday.

New Zealand and Scotland provide the opposition for one-day internationals on 1 and 2 July.
