One of the Jets’ strengths — their secondary — could be a weakness Sunday in Denver.

Coach Robert Saleh ruled out cornerbacks DJ Reed and Brandin Echols on Friday, creating uncertainty at the No. 2 corner spot opposite Sauce Gardner.

Saleh had been optimistic that Reed (concussion) would be able to play against the Broncos, but he has yet to clear the protocol.

Saleh was tight-lipped on the plan in the wake of the news.

The Jets could move standout slot cornerback Michael Carter II to the outside even though he has rarely played there in his short professional career.

Another option is going with backup Bryce Hall, who has played just four defensive snaps all season.

He will almost certainly see his role expand now.

“I have confidence in all the [defensive backs]. Whether it is moving people around, however we have to shuffle it,” Saleh said. “We have a lot of guys who have played a lot of football in this league and have played at a very high level.”

Losing the 26-year-old Reed is obviously a major blow, particularly from a leadership standpoint.

Carter singled him out as a player who solves a lot of problems for the defense, a high-level communicator who had 12 passes defensed a year ago.

Carter declined to offer much insight into the Jets’ plan, and neither did Gardner or Hall.

Carter said he is comfortable playing on the outside, pointing to the reps he received there during training camp and spring workouts.

“I’m in the corner meetings,” Carter said. “It’s kind of like a different point of view, I guess, from what you’re seeing from the field. You’re covering people and doing that stuff, a little less involved in the run. But there’s no real difference for me.”

A fifth-round pick in 2020, the 25-year-old Hall enjoyed his best season in 2021.

Starting all 17 games that year, Hall had 16 passes defensed and notched 71 tackles.

But he appeared in just five games last season without a start following the additions of Gardner and Reed.

“You just prepare the same way,” Hall said. “Regardless of whether you’re the starter or not, you have a special teams role. Any time, you’re one snap away. … Honestly, last year there was a big part of the year where I didn’t dress or suit up. So any time I have the jersey on I’m grateful for that.”

The Broncos have a strong receiving corps, led by Jerry Jeudy and Courtland Sutton, and are averaging 25 points per game, 10th-most in the NFL.

Quarterback Russell Wilson has looked more like himself this year after a nightmarish first season in Denver, throwing nine touchdown passes compared to just two interceptions so far while completing 67.4 percent of his attempts.

He is third in the NFL in passer rating at 106.7.

The Broncos’ league-worst scoring defense has let them down during a 1-4 start.

“Those are two big pieces for the defense,” Gardner said, referring to Reed and Echols. “I have to make sure I’m locked in and doing my thing. … They have some good threats on the outside, good running backs. It’s going to be a huge test.”
