The veteran opener did not train with the rest of the squad at Napier's McLean Park on Wednesday, remaining at the team hotel to rest.

"We'd love him to play all the games but we'll just have to manage him better," said coach Stuart Williams told local media.

Gayle, 35, blasted a World Cup record 215 in the win over Zimbabwe but his form in other games has been patchy with 36 against Ireland, four in the game with Pakistan, just three in the loss to South Africa and 21 facing India.

West Indies have just four points from five games after two wins and three defeats and need to beat the UAE handsomely to boost their run rate if they are to have any hope of squeezing into the quarter-finals.

Ireland and Pakistan, both on six points -- two ahead of the West Indies -- clash in Adelaide on the same day.

"Our destiny is in our own hands and on Sunday we'll know exactly what we'll have to do to qualify," added Williams.
