England Twenty20 captain Stuart Broad will miss the rest of the series against West Indies with a knee injury, and admits he may eventually need surgery to solve the problem.
He insists, however, that another injection to treat the long-standing problem will ensure he is fit to lead his country in the impending ICC World Twenty20 in Bangladesh.
England, who are likely to be led by Eoin Morgan in Broad's absence in the final two matches in Bridgetown, slumped to a 27-run opening victory after failing to handle the home spinners.
Marlon Samuels hit an unbeaten 69 and then took two wickets as he and Samuel Badree (three for 17) did most of the damage - and England replied to 170 for three by mustering only 143 for nine.
Of still more concern afterwards, however, was Broad's injury.
"I've got some patella tendinitis in my right knee," he said.
"I've had it all winter. It's just been a managing thing all winter, but obviously the workload has been quite heavy for me - and it's gradually got a little bit worse.
"I caught my knee in the sand in (the one-day international series in) Antigua, which has brought a lot of fluid into it.
"So there's not much movement in there, and I'll be missing the next two Twenty20s to have an injection to get right for the warm-up games in Bangladesh."
Broad expects, after several injections on the same joint already, a rest period - or perhaps even an operation - will be needed in the long term.
"I'll have to have a rehab period at some stage in the next 12 months, between six to 10 weeks.
"But there's a decent period at the end of the English season which I can look at probably - or maybe four weeks in April.
"But it won't put me in doubt for the (Twenty20) World Cup.
"It's just got to the stage at the minute where I can't move, so I need to treat it before then.
"It's something I need to try to get rid of."
Morgan (knee) and fellow batsman Joe Root - likely to be ruled out of the World Twenty20 on Monday after breaking his thumb - are England's other injury concerns.
Broad added: "The injection is a little bit of a risk, because it's the fourth or fifth one I've had - so you have to be a little bit careful.
"I hope it'll be okay for the English summer, get through that.
"Then I'll have to either 'rehab' it, or go under the knife."
He exacerbated the problem in England's ODI series victory last week, and likened it to an injury West Indies' key spinner Sunil Narine appeared to suffer in this Twenty20 at Kensington Oval.
"I just was running back at mid off, went to flick the ball up and my knee just got caught - a little bit like Narine today, I suppose - and it immediately hurt.
"Loads of swelling came into the knee, so it's really puffy ... I'm struggling to run at the minute.
"It's just deteriorating so much we needed to get something in it.
"I can't keep waking up every day in agony, and surviving training. The injection should sort that out, and if it means missing two Twenty20s in the West Indies when we've got a World Cup in Bangladesh I'm not too frustrated about that."
England may be equally worried, if privately, at their unpromising performance here.
Only Ravi Bopara, and belatedly Tim Bresnan's career-best 47 not out, kept the scoreboard respectable.
Bopara also appeared to anger Samuels at one stage, although the Jamaican insisted afterwards he had forgiven his opponent.
"It was a small comment. He said something he shouldn't say, but in the end he said he was sorry," he said.
"Ravi is a very wonderful person, and I always have a good relationship with him.
"It was probably the heat of the moment that he said something."
Samuels, who is currently banned from bowling his quicker ball because it is deemed to be an illegal delivery, declined to elaborate further.
Broad said of the incident in England's failed chase: "It was to do with Marlon.
"It looked something to do with a delivery Marlon bowled, etcetera ...
"He obviously was a bit frustrated at something, and I don't think it got cleared up particularly in the middle."
Narine is expected to have a scan on his injury on Monday.
