"It's been an honor to represent my country for 16 years. It's something I had always wanted to do since I was a child. During my career, we've gone from an amateur team right through to now being a Test nation.... All I ever wanted to do was leave the shirt in a better place and leave the team in a better place, and hopefully I've played a part in doing that,” said Porterfield.
Porterfield, who will take up a coaching role with Gloucestershire, played his last international in January at Jamaica's Sabina Park.
"I've been given the opportunity to join Gloucestershire as a Consultant Coach until the end of the season, and these opportunities don't come around very often," he said. "It's a decision I've been thinking long and hard about over the last week or so - and I'd like to thank Cricket Ireland for allowing me to get up and going in the role over the last while,” Porterfield signed off.
