The skipper suffered a stress fracture to the fourth metatarsal of his left foot in the closing seconds of Saturday's win over Everton at Goodison Park and has been ruled out for three to four weeks.
It is missing out on the run-in to our season's conclusion that is causing Ledley anguish at the moment, but he does have his World Cup ambitions to focus on.
"It is an exciting time for the Club and one that I was looking forward to," said the central defender. "It is what you want to be involved in coming up to the end of the season, big games against Manchester United, Arsenal, Bolton and West Ham - games that we need points from.
"For a footballer they are the kind of games you want to play in and I am disappointed to be missing out.
"I have been asked in the past months about the World Cup and how devastating it would be to get injured, but I wasn't thinking about anything like that. You play your football and each time you go out there and play your game you can't think about picking up knocks.
"It is just bad luck that I've got injured at this point. I will still be supporting the lads for the rest of the season," he continued, before adding that his strength of mind will see him cope with the hurt of not being on the pitch with so much riding on the next few games.
"I am strong, I have had injuries and setbacks in the past. I am disappointed, but I will stay strong and positive in order to get back as soon as possible.
"There is obviously the World Cup so it is not the end of the season for me when the Premier League stops. It is something for me to aim for."
The fact that the season is ending earlier than before to provide the national team squad with a clear month before the tournament begins is something Ledley believes will work in favour of himself and others who pick up injuries over the next few weeks.
"The English league is so competitive and it is a long season. Players get injured through the season and you never know at what stage this will happen.
"It is good that there is a little bit of time between the season finishing and the World Cup to give players a chance - and I fall into that bracket."
Even though he concedes his domestic season is likely to be over, Ledley King is confident he will be playing football again this summer.
