New England Patriots tight end Rob Gronkowski might have suffered another ailment that could threaten his playing time.
Gronkowski suffered what is believed to be a punctured lung in Sunday night's 31-24 loss to the Seattle Seahawks, according to NFL Network's Ian Rapoport.
His timeline for return was unclear, though he could miss just one game, according to Rapoport. The Patriots play the San Francisco 49ers on Sunday.
During the second quarter, Gronkowski took what he later called "one of the hardest" hits in his career when he was struck by Seahawks safety Earl Thomas on an incompletion. He played throughout the game and was targeted on an end zone fade that fell incomplete in the final seconds to seal the Seahawks' win. He finished with three catches for 53 yards.
Gronkowski missed the first two games of the season while dealing with a hamstring injury.
