Malik Jackson handled the question without hesitation. His answer might help calm the nerves of fidgety Broncos fans wondering whether it could happen again. Jackson, a Denver defensive end, immediately knew the reason for the question when he was asked if the defense has been worked on stopping the Hail Mary pass. He didn't need any reminders of Baltimore quarterback Joe Flacco's 70-yard touchdown pass to Jacoby Jones against blown coverage that allowed the Ravens to tie the score at 35 with 31 seconds left in the fourth quarter a year ago. The Ravens won 38-35 in double overtime in the divisional-round playoff game at Sports Authority Field at Mile High. "We've worked on that all year in practice," Jackson said of defending the Hail Mary pass. "We worked on it last year. They just made a play. It makes you upset when they do that, when you've practiced stopping it." The Broncos face a different set of challenges Sunday against San Diego — namely, slowing what has been a potent Chargers running game. The 6-foot-6, 290-pound Jackson is a key figure in Denver's defensive game plan. "This year has been a huge year for me," Jackson said. "I came in wanting to show what I had learned (as a rookie last year). I started out playing sparingly. I started earning more playing time. I gradually grew up, and the season kind of went the way I thought it needed to go." Jackson leads the Broncos in tackles for lost yardage (11) and in quarterback hurries (15). Denver coach John Fox has been pleased.
