Stuart Broad will miss the rest of England's Twenty20 international series with West Indies due to ongoing knee troubles.
England's captain in the shortest form of the game appeared to be struggling throughout the 27-run defeat in Barbados on Sunday and later confirmed he was suffering with patellar tendonitis, commonly referred to as 'jumper's knee'.
With the World Twenty20 just around the corner, the seamer confirmed he will sit out the next two matches against West Indies in order to lead his side in Bangladesh.
"(The knee is) okay, I've had knee patellar tendonitis for a while now, throughout the winter, with the workload," Broad told Sky Sports.
"It just gets a bit stiffer and stiffer, and I caught my knee in the ground in Antigua during the last one-dayer...and it just swelled up.
"I struggled to move it a little bit so I won't be playing the next two T20s. I'll have a bit of treatment, definitely get an injection in to make sure it's okay for the World Cup."
Broad expects to have recovered for the World T20. England start their campaign on March 22 against New Zealand in Chittagong.
"I should be okay, assuming the injection works, which generally they do. I've probably had four or five in that right knee now so you've got to be a little bit careful," he added.
"It's just gradually got worse throughout the winter with the amount of bowling I've been doing - no real break - so it's something I need to act on now to make sure I'm fit and firing for that World Cup."
Broad admitted England were caught out by the pitch after they were once again undone by slow bowling, raising questions about how suited they will be to the spin-friendly conditions in Bangladesh.
Leg-spinner Samuel Badree took 3-17 from four overs, while Marlon Samuels added two scalps with his off-spin, with England's seamers having earlier struggled.
"(The pitch) definitely played different. There was quite a bit of grass on the wicket and we saw that all the seamers went at about eight an over or more and all the spinners got wickets with low economy rates," he added.
"Whether that's to do with the batsmen not playing the spin particularly well or whether it's to do with it being very hard to play the spin, we'll need to analyse that.
"There will be some slower bowlers in the side come Tuesday, I think."
