Earlier this week, ESPN's Dianna Russini reported Gronkowski was not expected to play against the Jets. On Saturday, Russini reported Gronkowski "made a lot of progress in the last 24-48 hours" and cited two sources who referred to him as a "true game-time decision."
Gronkowski had been a limited participant in practice all week and is officially listed as questionable. Reporters saw him wearing a red noncontact jersey at the end of Friday's practice.
Gronkowski sustained the chest injury in a 31-24 loss to the Seattle Seahawks on Nov. 13. He missed the next week of practice and didn't make the trip last weekend to San Francisco.
