Season-ending knee injuries to defensive tackles Henry Melton and Nate Collins have prompted the Bears to move Corey Wootton to tackle from defensive end. He's still adjusting to playing closer to the ball. "You get a lot more double teams," Wootton said. "Guys are shorter and stouter, really good run blockers. Contact happens faster than outside, so it's definitely an adjustment." Wootton plans to establish power on his rush by taking a shorter first step after the ball is snapped. That's necessary to account for the reduced space between him and the offensive guard than between him and the offensive tackle when he lined up on the end. "The biggest thing is you just have to take a shorter 6-inch step and really get your feet in the ground," he said. "If you take too long of a step, they're really going to be able to get you off balance. I got the hang of it during the game." Defensive coordinator Mel Tucker was pleased with Wootton's work at three-technique in Sunday's loss to the Saints. "He was able to get his pads down, use his hands and get off the ball, had good anchor and played with good energy," Tucker said. "He's a smart player. He has good football awareness and instincts. He can bend. He's strong. He has anchor. He has length. He can do both (end and three-technique)." Extra points: Cornerback Charles Tillman (right knee) and safety Anthony Walters(left hamstring) would not have participated Tuesday if the Bears had practiced instead of having walkthroughs. … Defensive tackle Stephen Paea (sprained toe) would have been limited, an upgrade from his status Monday. Tight end Martellus Bennett (left knee), receiver Alshon Jeffery (ankle) and left tackle Jermon Bushrod (calf) also would have been limited. … Giants leading rusher David Wilson (neck) will not play Thursday night against the Bears, coach Tom Coughlin announced. Brandon Jacobs will start. … The Bears terminated the practice-squad contract of defensive end Aston Whiteside to make room for defensive tackle Christian Tupou. I honestly like this, but McClellan HAS to start showing up since he's likely to take over as starter for the DE spot.
