The 49ers have signed the tight end to a five-year extension through the 2021 season. The new deal is worth $35 million, a source informed told NFL Network Insider Ian Rapoport.
"Vance has shown consistent growth throughout his four-year career and his production this season is the result of his dedication and hard work," 49ers general manager Trent Baalke said in a statement. "We believe he has only scratched the surface of what he will be able to accomplish in his career."
McDonald is in the midst of a career-best season, already racking up highs in yards (391) and touchdowns (4) through 10 games played. He's averaging 16.3 yards per catch, the 10th-highest mark in the league and is only behind Rob Gronkowski in the metric amongst all tight ends. The former second-round pick started to hit his stride with the offense after the team traded Vernon Davis last year.
