Despite three turnovers and a missed field goal in the first half, the Lions rebounded to dominate the Packers, earning their first win on Thanksgiving Day since 2003. After David Akers and Mason Crosby exchanged field goals, Green Bay took their first and only lead of the day in the second quarter when Nick Perry forced a Matthew Stafford fumble that Morgan Burnett returned for a 1-yard touchdown.  Detroit tied the score at 10 after Stafford found Jeremy Ross in the end zone with a 5-yard TD pass. A 1-yard Reggie Bush TD run gave the Lions a 17-10 halftime lead. The second half was all Lions. Calvin Johnson hauled in a 20-yard pass from Stafford for a 24-10 Lions lead.  Late in the third quarter, Ndamukong Suh sacked Matt Flynn in the end zone for a safety. After the ensuing free kick, Joique Bell finished off a 56-yard drive with a 1-yard TD run to put Detroit up 33-10. Kevin Ogletree completed the scoring by catching a 20-yard TD pass from Stafford to account for a 40-10 final score. Matthew Stafford was 22-of-35 passing, hitting nine different receivers for 330 yards and three touchdowns, while Reggie Bush had 182 yards from scrimmage (117 rushing, 65 receiving). With 101 yards receiving in the game, Calvin Johnson now has 4,944 receiving yards over the 2011 to 2013 seasons, surpassing Jerry Rice's previous NFL record for receiving yards over a three-season stretch (4,850 yards from 1993-95). The Lions offense outgained the Packers in the game 561 yards to 126 yards, while Detroit's defense sacked Matt Flynn seven times.
