Pittsburgh's Tommy Maddox, Philadelphia's Donovan McNabb and Denver's Brian Griese won't be able to help their teams for a while after being injured this past weekend.
Maddox, injured Sunday in Pittsburgh's 31-23 loss in Tennessee, was up and walking again before being released Monday from a Nashville hospital. He has concussions to the brain and spinal cord, but no structural damage.
McNabb could miss the rest of the regular season and possibly the playoffs with a broken right ankle. And Griese's sprained left knee will keep him out of Denver's lineup against Indianapolis next weekend and could sideline him for three weeks.
Maddox hasn't been cleared to play -- he was admitted to a Pittsburgh hospital Monday night for more precautionary tests -- but the Steelers are relieved and optimistic he might return later this season.
At least 15 minutes passed Sunday at The Coliseum while Maddox was turned onto his back and strapped to a backboard after trainers cut off his face mask. Maddox was unconscious for about five minutes but never stopped breathing.
