A person with knowledge of the negotiations says the New England Patriots have picked up the option that will keep Pro Bowl tight end Rob Gronkowski with the NFL team through 2019.

The person spoke to The Associated Press on the condition of anonymity because the Patriots had not announced the move.

The 26-year-old Gronkowski alluded to the move on Monday when he tweeted that he was taking a pay cut for the next four years. The deal made in 2012 was a six-year extension worth $54 million US, including a $10 million option that would activate the deal for 2016-19.

The Patriots paid $4 million of that option last year, making this week's move a formality.

Gronkowski was the team's leading receiver this season, with 72 catches for 1,176 yards and 11 touchdowns.
