Mack (ankle) returned to practice Friday on a limited basis after missing Wednesday and Thursday, and is designated as questionable for Sunday's game against the New England Patriots.
The Bears' outside linebacker suffered the ankle injury in Week 6, but played through it. He entered the week considered day-to-day before Friday's practice.
Mack, who is capable of dominating a game, would certainly help the Bears defense. But just don't compare his game-changing skillset as a pass rusher to Hall of Famer Lawrence Taylor.
The Bears also list cornerback Marcus Cooper (hamstring) as doubtful and wide receiver Allen Robinson (groin) as questionable.
