Louie Simmons has broken his back and come back.
Brandon Lilly came back from having his patellas explode.
Jason Pegg took an IED to the elbow and still smashes weights.

Depending on the severity of your injury, the resources you utilize, your patience and your drive you may be fine. Listen to the Drs, if they tell you that you'll never train again, go see someone else and repeat until you find someone that says "we will get you training again to some degree" then go from there.
