Joe Root has been ruled out of the three-match Twenty20 series against West Indies after suffering a broken right thumb in Wednesday's ODI victory.
The Yorkshire batsman was struck on the hand by a steepling Ravi Rampaul delivery early in his innings in Antigua, but batted on after treatment to make a brilliant 107 as England claimed a 25-run victory and a 2-1 series win.
However, a scan on Thursday has confirmed he suffered a fractured thumb and will return to England to see a specialist, leaving him a doubt for the ICC World Twenty20 in Bangladesh next month.
Root's absence will be keenly felt by England as his off-spin has been increasingly exploited by England's limited-overs teams and he opened the bowling with success in the 50-over format in the Caribbean.
The news completes a difficult winter for Root, who was dropped from the Test team at the end of the Ashes and struggled for runs throughout the tour of Australia.
After the series-clinching victory, England captain Stuart Broad reserved special praise for the batsman, saying: "It was an incredibly brave knock.
"He came off, and his thumb was very ugly. Eoin (Morgan) was going to go out after the rain break. But then two minutes before, Joe put his helmet on and stormed out.
"I think it was clear for everybody to see the discomfort he was in. To battle through that and go and get a hundred ... that's the sort of commitment and desire you want guys to have playing for England."
Ian Bell has already been added to England's T20 squad in Barbados following injuries to batsman Eoin Morgan and Alex Hales but it remains to be seen whether the ECB will call for further cover as Root returns home.
