Hi, as you know that any degree related to medicine needs too much time and attention. Not saying that you can not become one because you can. Almost every college entertains students who excel in sports as it brings name and fame to them. Like you there are several others who wanted to do it like you. If you have what it takes to be both than you will. Try to find out what another medical student named VVS Laxman did to become a cricketer maybe  you could follow a similar path. If you still have doubts feel free to comment. Hope this helps.
