The shoulder injury that has bothered Bears running back Jordan Howard all season might have changed the way he runs with the ball for a time. Howard admitted as much Sunday, saying that he returned to his “violent ways” after protecting his shoulder earlier in the season. Howard — who ran for 147 yards on 23 carries after totaling 44 on 20 in the previous two games — has yet to miss a start because of injury. But coach John Fox was asked Monday whether there’s a fine line between letting Howard play through pain and allowing it to change his style. “There’s guys that sometimes have to be more 100 percent to play. Jordan’s not one of those guys,” Fox said. “Not that you’re going to re-injure yourself, but it does affect how you practice and obviously how you play the game.”
