Driver is listed as "out" for Sunday's game vs. the Detroit Lions at Lambeau Field. That comes as no surprise after Driver spent two days in the hospital for a severe neck sprain, aggravated by signs of concussion.
Driver is expected to be back in the lineup at least in time for the Monday Night matchup vs. the Bears in "new" Soldier Field Sept. 29, Sherman said.
That's a slightly conservative time table, as there's still a chance Driver could play when the Packers travel to Arizona in Week 3.
Quarterback Brett Favre, also meeting the press Wednesday, echoed Sherman's sentiments about Driver.
"Donald's a great player, and he helps this football team, but do I want to rush him back so he can further injure something?" Favre said. "I want him back as soon as possible, but I want him healthy."
