Ireland captain William Porterfield won the toss and chose to bowl against the West Indies in their World Cup clash at the PCA Stadium in Mohali on Friday.
The West Indies have brought in Andre Russell for Chris Gayle who is suffering from an abdominal strain.
Ireland have replaced the injured Trent Johnston with Andre Botha.
Porterfield said that it's a morning game so it will help the fast bowlers. They have taken confidence from the earlier games.
West Indian captain Darren Sammy said that Gayle will be ready for the next game. Chanderpaul would be opening with Devon Smith so there is no lack of experience. It's upon the boys to be consistent and execute the plan well. They have a very good team spirit.
The West Indies were well beaten by South Africa in their tournament opener but responded by thumping the Netherlands and demolishing co-hosts Bangladesh in Dhaka, bowling them out for just 58.
The bowling star for the West Indies has been fast bowler Kemar Roach who took 3/19 to add to his 6/27 against the Netherlands.
Other bright spots in the tournament have been the bowling by giant spinner Sulieman Benn and the potential shown by batsman Darren Bravo.
The West Indies have four points from three matches in Group B, the same as South Africa but trailing India and England, with the top four sides from each group qualifying.
Ireland's win over England, in which they scored 329/7 to win the game, meant they leapfrogged Zimbabwe in the one-day international rankings, moving into 10th place.
Ireland are fifth in Group B with two points.
Ireland bowled and fielded superbly against India while defending a modest total of 207, reducing India to 100/4 before Yuvraj Singh guided his side home with an unbeaten 50.
