"I have played 12 years for the national team. I am now 32 and will soon be 33. I have had a bad injury and if at this stage I have to take one or one and half years of rest, I would rather have to finish my career. If I need to play tough cricket for my country, I don't think I can then totally recover from the injury. That's why I am saying I don't know how many months or years are left in me. Whatever little I play, I want to serve the national team and my IPl team (Mumbai Indians) well," Malinga said.
