The Jets will be without starting wide receiver Quincy Enunwa for the rest of the season, The Post has learned.

Enunwa suffered a neck injury in Sunday’s season-opening loss to the Bills and will not be able to return this year. This is the second serious neck injury Enunwa has suffered. He missed the entire 2017 season after injuring his neck in training camp that year. It is unclear whether this injury is considered career-threatening.

Enunwa left Sunday’s game in the first quarter briefly and then returned. He only had one catch for [minus]-4 yards in the game and was targeted just three times.

A source said Enunwa went for tests Monday, which revealed the seriousness of the injury and that he would be out for the year.

The trade for Demaryius Thomas on Tuesday now makes more sense. The Jets sent a 2021 sixth-round pick to the Patriots for the 31-year-old veteran receiver. It was initially thought to be just a move to add some depth to a thin position group. Now, it is clear the Jets were trying to find someone to replace Enunwa in the lineup.
