James Cook, Bills reach 4-year, $48M extension after RB's hold-in - ESPN

Running back James Cook and the Buffalo Bills have reached agreement on a four-year, $48 million contract extension that includes $30 million guaranteed, his agents, Zac Hiller and Matt Leist of LAA, told ESPN's Adam Schefter on Wednesday.

Cook's $30 million guarantee is highest for a running back in the past five years.

The extension comes a day after Cook returned to Bills practice Tuesday following a four-day hold-in that included the running back missing Buffalo's first preseason game.

«James could only envision himself as a Buffalo Bill,» Hiller said. «We are extremely thankful to the entire Bills organization and glad we could make that happen.»
