Zach Wilson remains in concussion protocol, Jets head coach Robert Saleh said Wednesday.

Asked about Wilson’s potential availability for Sunday’s game against Washington, Saleh said, “We’ll see. I’m not closing the door.”

Wilson left last week’s loss to the Dolphins before halftime with a head injury and will have to go through several more steps in order to be eligible to play Sunday.

He’ll likely need to be back on the practice field, at least in limited form, Thursday to have a chance to face the Commanders.

Wilson’s mother, Lisa, said in an Instagram post Monday that Wilson didn’t tell the coaching staff or medical team about the extent of his symptoms until he began suffering blurred vision and issues with his depth perception.

Asked about Wilson not being pulled until after those occurred, Saleh said, “Sometimes we don’t always catch [head injuries]. That’s why we have NFL spotters. But players do not want to come off the field. We always encourage them to communicate.”

He also noted Wilson’s competitiveness.

“Credit to Zach, he will fight,” Saleh said. “I always say, no matter how many hits he’s taken, how many times he’s running for his life, he always comes back to the huddle and he’s come back and he’s fought. I have a great appreciation for him, but at the same time, thank goodness it was spotted and we could get him the care he needs.”

If Wilson is unable to go, the Jets would again turn to backup QB Trevor Siemian, who replaced Wilson against the Dolphins following his departure.
