Matthew Stafford has signed a $53 million, three-year extension to stay under contract with the Detroit Lions for at least the next five seasons.
Stafford and the Lions agreed to terms Tuesday on the deal that will pay him another $41.5 million in guarantees, and he signed the contract Wednesday morning.
Detroit drafted Stafford No. 1 overall in 2009 and signed him to a six-year contract worth as much as $78 million with $41.7 million in guarantees. After two injury-shortened seasons, he helped the franchise reach the playoffs in 2011 for the first time in more than a decade.
Stafford threw more interceptions and had 21 fewer touchdown passes in 2012 than he did the previous year.
