Rob Gronkowski will not attend the start of the New England Patriots' offseason program on Monday.
Gronkowski still is considering whether to play the upcoming 2018 season, and has had "good communication" with the Patriots.
Gronkowski has a $250,000 workout bonus in his contract for 2018 that is tied to attending a percentage of the voluntary workouts.
Tom Brady also won't attend the start of the offseason program. Brady has been on a business trip to Qatar.
