Kyle McCallan will be captain for the ODIs, as well as for the Ireland A Twenty20 match against Bangladesh A, on June 27, and the 50-over match on June 29. Trent Johnston, the former captain, will return to Ireland colours for the Twenty20 clash at Eglinton. Kevin O'Brien, the allrounder, had already been ruled out with a hamstring injury.
O'Brien has been keeping and opening the batting during the Twenty20 Cup, while Porterfield, who fielded as a substitute for England against New Zealand at Bristol, has found an opportunity in the Gloucestershire top order after injury to Craig Spearman,
"It's definitely the hardest decision I've ever had to make, and I didn't think it would come so early in my time at Gloucester," said Porterfield. "I'm just embarking on my professional career, and trying to cement my place in the team.
"The 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 in my career."
Coach Phil Simmons admitted that losing two key players wasn't ideal, but still backs his squad to cover for their loss. "I understand his [Porterfield's] 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."
