As a player dealing with injuries is extremely hard, if its a rolled ankle or a serious injury like a torn ACL it is tough physically, emotionally and psychologically. Sitting on the bench watching your team is hard but coming back is even harder. 

Coming back from a sprained ankle can be difficult because your off your feet for a few weeks and even when your good to go and play your ankle sometimes still feels like there is a little tweak. 

However coming back from a serious injury is especially hard, I have come back from a back injury which could have left me paralysed and an ACL, MCL, and Meniscus injury which could still keep me from playing the sport I love at the level I want to. 

When walking onto the court after going through the journey of having a major injury is emotionally and psychologically hard. That first time back on the court there's a lot that goes through your head, everything from how that injury happened to the extremely happy thought that you can still play. 

The first thing a player needs to do before playing in a game or practice after a major injury is start using the treadmill or bike and lifting weights, your muscles and cardio will go to waist extremely quick. Once back into game shape make sure you get on the court and practice what you were doing when you got injured. Believe me this is not always the easiest thing to do. 

When I injured my back I was on a fast break when I jumped up to dunk but as soon as I jumped up a defender caught up and gave me a hip check and I was flipped and landed on my neck. It took me 15 minutes to walk to the other end of the court to leave. When returning to the game I had a very hard time to drive on players. It's hard to explain, I knew I could drive on the player but before I could drive I would stop myself. What helped me was a friend offered to play shadow defence on me so I can get used to driving on players again (I was off the court for 2 months started shooting for 2 months after and after the 4 months I returned to the game). The nurses told me I was lucky, I could have been paralysed.

I am now 1 month out of ACL Reconstruction surgery and looking to get back the court in 3-6 months from now. I have gained lots of weight with this injury which is something many athletes deal with after a major injury, especially an injury that keeps you off your feet for so long (once I can return to Basketball I will be out of the game for 2 years). I have set my goal to be down 40 pounds before I step back on the court.

Now I am not complaining about my misfortune however these are great examples for athletes who are injured. 

I hope this helps.
