fair thing to discuss IMO. Nadim has the most imp question...its clear he has to have the surgery, but how long will the recovery take is the only issue. Is he having athroscopic surgery with micro-incisions or more traditional surgery? Since he doesn't seem to be debilitated as is, the surgery is most likely minor and recovery time should only be a matter of weeks and not months. If its not affecting him too much (doesn't look like it) and there is no major risk of aggravating it, he should wait till after WI series. thats a very important series and he shouldn't risk not recovering in time so long as the ailment isn't crippling - which judging from his 84 and bowling today doesn't appear to be so bad.
I drop knowledge so heavy it leaves the world unbalanced, exterminating the spiritual force of all that challenge, I'm the lyrical apocalypse that crumbles the granite, replacing you as the dominant species on the planet.
