I'm always hesitant to do direct comparisons since most sports are so different in what they expect mentally and physically of athletes. Further complicating comparisons are specific genetic makeup and treatments and such. With that sad, Spanish cyclist Alberto Cantador had a cavernous malformation that caused him to collapse in a race in 2004. In 2007 he won the Tour de France, and continues to be a dominant cyclist.
Yeah, but how do we get RWM to start blood doping
I think that this is an optomistic comparison and definately something to look to in hopes of RWM returning to Baseball. We have all heard about his work ethic and positive outlook on life which lead to positive thoughts and feelings for this kid.
Like others have said though, it really depends on the location and how much damage may have been done during the surgery and or general disease process. There appears to be an article in the British Sports Journal
about a rugby player returning to the sport. I am not sure if it is helpful as I don't have access to the article nor am I medically trained so I don't understand some of the language. Perhaps some of our doctors can weigh in?
