They may be back, but will they play - will they play much? Will they be rusty and out of condition some? Will Demarcus "Burlington Coat Factory" Granger have to win his spot back from Cory Bennett? We will see....
If Granger even plays in the game he will only risk injuring himself more if he tries to get back too quickly. They'll suit up for the game and may even play a series but I wouldn't expect anything more than that.
Even minor leg injuries are pretty debilitating to a DL for the entire season. It's all leg strength, pushing and shoving, and getting hit over and over again in the legs, getting fallen on, etc. It's just oo hard to fully heal in mid-season. They may be able to play, but they are no longer exceptional because of the injury. Think Frank Okam in 2006.
