Gronkowski threatened to retire upon hearing the trade talks.
Patriots tight end Rob Gronkowski confirmed a report that the Patriots and Lions were in trade discussions during the offseason.
Following the Patriots' 26–10 loss to the Lions on Sunday, Gronkowski said, "Yeah, it happened. Brady's my quarterback."
ESPN's Adam Schefter reported the news earlier Sunday, saying Gronkowski threatened to retire if he was traded from New England. The four-time All-Pro refused to return calls from the Lions, stating he'd rather hang up his cleats than play for another organization.
The Patriots opted to hold onto Gronkowski, agreeing to a revamped contract that added $4.3 million in incentives to his 2018 deal.
The 29-year-old tight end has hauled in nine catches for 138 yards in New England's first two games this season. Gronkowski has 77 career touchdown receptions, third all-time among tight ends. He finished Sunday with four receptions for 51 yards.
