The Patriots say tight end Rob Gronkowski is questionable to return to the AFC championship because of a head injury.
Gronk was left wobbly on a hit from Jaguars safety Barry Church on a downfield pattern late in the first half. Gronkowski headed to the locker room and sat out the remainder of the first half.
He did not appear to be on the New England sideline when the second half began.
Earlier in the second quarter, Gronkowski caught a 21-yard pass that moved him past Dallas Clark for first on the NFL's all-time list for postseason receiving yards by a tight end, 848.
