This isn't good, when he decides to shoot, which he does very well, it's very key to Grizzlies victories. I hope it gets better and that it isn't too serious. Especially since he's so young, however if it is, let's hope he's like Wade and can play well even after coming back from injury.
I don't think he'll be a Tom Gugliotta, playing like crap after an injury. The hopes will be on him not turning into another Grant Hill. I don't know much about it but I sure hope it isn't that serious.
Back injuries are pretty serious, and there's not a lot modern medicine can do to treat them effectively. Just let him rest up for the playoff run. We've been doing well enough without him.
