The Dallas Cowboys have locked up one of their most dangerous offensive players, signing tight end Jason Witten to a five-year, $37 million contract extension, NFL Network's Michael Lombardi confirmed Sunday through a league source.
Witten, a seven-time Pro Bowl pick, received a deal that includes $19 million in guaranteed money. He's now under contract through 2017.
"I am blessed to say that I will retire a cowboy!," Witten tweeted Sunday morning. "Thx to the jones family, and all the cowboy staff! True honor to put on the star!! #gameday"
ESPN first reported news of Witten's extension.
Witten, 29, has been one of the most productive pass-catching tight ends in football since being selected in the third round of the 2003 NFL Draft. Last season, Witten tallied 94 receptions for 1,002 yards and a career-high nine touchdowns.
