Stephen Paea had plopped down on the bench Thursday night when someone screamed for the defense to run back on the field. “I was like, ‘Didn’t they just kick the ball off?’ ’’ the defensive tackle said. The Jacksonville Jaguars had, but Eric Weems fumbled the first-quarter kick, sending the defense back to their marathon first frame. The Jaguars ran 26 plays against the Bears’ defensive starters in the first quarter alone. The Bears had eight. Against the starters, the Jaguars scored 13 points — two field goals and, after the fumble, a touchdown — in a game the Bears rallied to win 20-19.
