Symonds is considered a valuable member of the Australian side not only because of his explosive batting but also because he is regarded as one of the world's best fielders.
  
"There is a small risk of re-injuring it and, obviously, the longer it is left, the less the risk becomes. There will always be some risk," James told The Sydney Morning Herald on Thursday.
  
"The effect of that, from a theoretical point of view, is that  it may lead to approximately a 10 percent reduction in strength, and  that may be something he notices more with throwing than anything  else.
  
"But it wouldn't mean that he wouldn't be able to continue playing cricket at the level he is playing.
  
"The thing is that his throwing is such a wonderful part of his skills that if he did lose that, it might make him more at the level of other cricketers rather than stop him from playing."
  
Symonds, who had surgery to re-attach the tendon, will continue a rehabilitation programme in the Caribbean with team physiotherapist Alex Kountouris.
  
"The shoulder is starting to heal quickly. I was told if I was going to have problems with it after the surgery, like shoulder freeze or problems with the joint, it would have been in the first 10 days," Symonds said.
  
"It hasn't done that and it feels really good which hopefully is a good sign of quick healing.
  
"The World Cup is a big deal to me. It's not the end of the world if I snap it again. It can heal and be OK. So I'm not too worried about it if it goes again, because I know it will be OK. If it goes, it goes.
  
"I've been told I've got to think long-term but I tend to think I'll go one thing at a time. I will play, hopefully, half of the World Cup - if not more."
