Kroft sustained a lung laceration in Thursday's loss to the Colts and is expected to miss multiple weeks, Ian Rapoport of NFL Network reports.
New York expects Kroft to return this season, but he'll presumably be moved to injured reserve next week, meaning that he'll be forced to sit out at least three games. With Kroft out of the mix, Ryan Griffin -- who logged a 4-28-1 stat line on seven targets Thursday -- and Trevon Wesco (two catches for 16 yards) will serve as the Jets' top two options at tight end.
