I feel like it's pretty much a given. Once you have back problems it stays with you for life. Mine started at age 14. It can also be set off by anything, I once threw my back out just opening the oven door. That's ridiculous. Just because his back is tweaked doesn't mean he'll have the problem for life. I don't know that it's a given either for sure, but he has missed multiple games at least three times in his career due to his back. At the very least, it's quite concerning to be happening to a guy who is still only in his 20s.
