In this photo taken Sept. 19, 2010, Chicago Bears quarterback Caleb Hanie appears during an NFL football game against the Dallas Cowboys in Arlington, Texas. If Jay Cutler has a recurrence of concussion symptoms, his replacement might not be journeyman Collins, who threw four interceptions in a win at Carolina as Cutler recovered, but Hanie.
