England skipper Stuart Broad will miss the remaining two Twenty20 matches against West Indies with a knee injury.
Broad is now an injury doubt for the ICC World Twenty20 tournament later in March after aggravating his knock during Sunday's 27 run defeat in Barbados.
The England captain has been suffering from patellar tendonitis and may be given injections to speed up his recovery.
"I've had a patellar tendonitis problem in my right knee for quite a long time," Broad was quoted as saying by BBC Sport.
"With the workload I've had all winter I've not really had any breaks, so it's got worse and worse.
"I just caught my knee in the sandy ground at Antigua and got a lot of inflammation and fluid on it. It was touch and go today, but I won't be playing the next two games, and I'll have to have some kind of injection to get me through the World Twenty20, I'd think."
England have two more games in Barbados on Tuesday and Thursday ahead of their opening game of the World T20 against New Zealand on 22 March.
West Indies stormed to a 170-3 lead in their first 20 overs on Sunday having won the toss before restricting England to 143-9. Tim Bresnan hit 47 in the best of the tourists' attempts to reduce their deficit but never really looked like getting close to their target.
Vice-captain Eoin Morgan will lead England in Broad's absence in their remaining matches in Barbados.
West Indies also have slight injury concerns ahead of their World Twenty20 opener against India on March 23 as spinners Sunil Narine, the world's top ranked T20 bowler, and Samuel Badree limped out of the action on Sunday.
"Our physio is monitoring it very closely, "West Indies captain Darren Sammy said of Narine's knock. "So far from his reports, it doesn't look like ligament damage but he will go for a scan and we will see how serious it is."
