Rehabbing is literally defined as receiving treatment for an injury. Until you are 100% you are rehabbing. That's pretty much the same as hurt and not ready to go. We have probably a dozen players right now rehabbing one thing or another, just as virtually every other team in the NFL at this point of the offseason.

Oh, another definition for rehabbing is going through the recovery process for the abuse of drugs or alcohol. You might want to reconsider that t-shirt.
