The first was receiver Devin Aromashodu's drop of what should have been a 38-yard touchdown pass on the Bears' opening possession. The Bears later settled for a 20-yard field goal.
The second was Jay Cutler's ill-advised pass to receiver Johnny Knox on their second possession. Knox was surrounded by three defenders. Linebacker Julian Peterson tipped the ball to safety C.C. Brown, who tipped the ball to rookie cornerback Aaron Berry for the interception. The Lions took over at the Bears' 42-yard line and eventually capitalized on Jahvid Best's 7-yard touchdown run.
