Deandra Dottin will miss West Indies' tours of Ireland and England because of a shoulder injury.
Dottin, who recently became the No. 1 allrounder on the ICC's women's T20I rankings after being named Player of the Series during the February tour of Pakistan, needs surgery on her right shoulder and has been replaced by Britney Cooper in the squad.
Cooper has 422 runs from 40 ODIs with a strike rate of 57.18 and 452 T20I runs from 59 matches. She was part of West Indies' squad during the ICC Women's World T20 in the Caribbean last November. An agile fielder and big hitter, Cooper earned her place in preparations for the Ireland and England tours on the back of a strong showing in the Cricket West Indies Women's Championships in Guyana in March.
"She is certainly a key player for us and we wish her a speedy recovery to come back and win matches for the West Indies," interim chairman of selectors Robert Haynes said. "Britney has previous experience at the international level and we believe she will make a positive contribution."
West Indies are at a training camp in Antigua after being strengthened by the return of captain Stafanie Taylor, vice-captain Hayley Matthews, and pace bowler Shakera Selman from the Women's T20 Challenge in India.
They face England in three ODIs between June 6 and 13 and three T20Is between June 18 and 25. Before the England tour, they play Ireland in three T20Is starting May 26.
West Indies are seventh on the ICC Women's Championships points table with 11 points.
West Indies squad: Stafanie Taylor (capt), Hayley Matthews, Britney Cooper, Afy Fletcher, Karishma Ramharack, Chedean Nation, Chinelle Henry, Kycia Knight, Kyshona Knight, Shakera Selman, Shamilia Connell, Shemaine Campbell, Natasha McLean, Stacy Ann King.
