Darren Sammy admits the West Indies players are playing for their futures ahead of the five-match ODI series against New Zealand.
The Windies, who lost the Test series 2-0, have lost all-rounder Marlon Samuels to a wrist injury, while Chris Gayle and Kieron Pollard are also absent, leaving the tourists in some disarray ahead of the first match in Auckland on Boxing Day.
Crisis meetings have been scheduled for the team's return home, with Test skipper Sammy, already stripped of the one-day captaincy in favour of Dwayne Bravo.
And Sammy said: "There are tough decisions to be made by the coach and the director of cricket. Some careers are on the line, could be mine as well, you never know."
Samuels' absence will open the door for the relatively untested wicket-keeper-batsman Chadwick Walton, who has played in two ODIs without registering a run.
"Chaddy has been on tour with us from the start including the tour of India without getting an opportunity," said head coach Otis Gibson.
"He has been working hard and growing as a player, and I feel confident that when his opportunity comes he will make the most of it."
New Zealand are in much healthier shape, with Jesse Ryder ready to return having last played in February 2012 before being attacked in Christchurch in March.
"Jesse gives us added fire power at the top of the order and he has a proven international record," said head selector Bruce Edgar.
The ODI series gives Ryder the chance to press his case for a return to the Test side, although the top-order's impressive form in the long form of the game could make it difficult for him.
With India next up in February, Ryder must score heavily, with opener Peter Fulton perhaps the most vulnerable if Ryder can build on his recent domestic displays.
