Bears tight end Zach Miller had eight surgeries in a six-week span after dislocating his knee Oct. 29 against the Saints. He returned to Halas Hall on Monday, only a few days removed from being able to bend his left knee for the first time Friday. Amazingly, despite suffering an injury most consider career-threatening, he didn’t rule out wanting to play football again. “It’s possible,” he said with a smile. He said his major knee ligaments — the ACL, MCL and PCL — are “good,” and that he’s been told his knee was surprisingly intact despite the horrifying dislocation. “I haven’t really thought much of football from now on, you know what I mean?” he said. “I haven’t got to that point. For me right now, it’s just getting this right, getting healed up and when that point comes, make a decision.
