England will send Joe Root for an X-ray to discover the extent of the damage done to his right thumb during his match-winning century against West Indies.
The Yorkshire batsman registered his maiden one-day century in the third and final game of the series, despite taking a nasty blow off the bowling of Ravi Rampaul in the early stages of his innings.
He combined with Jos Buttler (99) to put on a 175-run stand to carry the tourists to a total of 303-6, with West Indies bowled out for 278 in reply at the Sir Vivian Richards Stadium.
Coach Ashley Giles is hopeful Root, who also took an early wicket with the ball before leaving the field, will be fit to play a part in the upcoming Twenty20 series against the same opponents.
"Joe's a worry," Giles said.
"He'll have an X-ray either tonight or tomorrow. Fingers crossed he'll be okay.
"It was a real lion-hearted effort from Joe. He got a nasty hit on his thumb and to get a hundred was a great innings."
Root himself was confident he would be fit to play on the rest of the tour, with the opening T20 taking place in Barbados on Sunday.
"It's a little sore but it should be all right," he said after being named both man of the match and man of the series at the presentation ceremony.
"It was nice to get a good partnership with Jos and end up with a decent score."
As for the series as a whole, Giles was delighted to have fought back from 1-0 down to enjoy some much-needed success after a tough winter in Australia.
"There's always plenty of work to do, but to get over the line is fantastic for the team," he added.
"It's been a tough few months for everyone so to win a series is a fantastic feeling."
