A shoulder injury has also ruled fast bowler Kemar Roach out of the 15-man squad, which will be led by all-rounder Darren Sammy.
"Neither Kieron Pollard nor Kemar Roach were considered for selection due to continued rehabilitation from injury," the West Indies Cricket Board said in a statement.
"Pollard continues to recover from a knee injury sustained late last year and Roach is still trying to get over a shoulder injury that forced him to return home from the tour of India without playing and required surgery."
West Indies won the last edition of the tournament in 2012 after beating hosts Sri Lanka in the final in Colombo.
