The all-rounder, who bowls left-arm spin, last played an ODI in October 2018 and was not selected in the preliminary 15-member squad announced in April.
However, rated as the third-best one-day spinner in the country, the 29-year-old has found himself parachuted in with over a week to go before England's opening fixture against South Africa on May 30th.
The squad will be announced officially today.
