Matthew Stafford’s career with the Detroit Lions just got longer. Stafford and the Lions agreed to terms on a $53 million, three-year extension to keep him under contract through 2017, according to a person familiar with the deal. The person, who spoke Tuesday to the Associated Press on the condition of anonymity because the agreement has not been announced, said Stafford will make $41.5 million in guarantees as part of a new contract. 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 two years ago for the first time in more than a decade . . . With two team executives facing drunken driving charges, the Denver Broncos acknowledged a ‘‘disturbing pattern of irresponsible behavior’’ that they vowed to clean up.

Word of his arrest came just one day after Broncos director of player personnel Matt Russell apologized for his arrest on suspicion of driving under the influence. Russell faces multiple charges including driving under the influence and careless driving resulting in injury after police said his 2008 Toyota Tundra crashed into a Breckenridge police SUV on Saturday night.
