The Philadelphia Eagles have announced a contract extension with tight end Zach Ertz, according to the team's official website.

The deal is reportedly worth $42.5 million, with $20 million coming in guaranteed money.

Ertz, 25, is now under contract until the 2021 season.

Ertz was a 2013 second round pick in Chip Kelly's first season as head coach and has not dissappointed. He has 169 receptions for 2,204 yards and 9 touchdowns. In 2015, Ertz got off to a slow start after undergoing groin surgery during the pre season.

Ertz tweeted a message about the extension shortly after the announcement:

"Nothing could make me happier than knowing I’m going to be a member of the Philadelphia Eagles for years to come."

With Ertz locked up, the Eagles will now, reportedly, shift their attention to Lane Johnson and Vinny Curry.
