Thursday, Justin Fields was carted off the practice field.

Immediately, panic swept through the tormented Jets fan base, worried their starting quarterback was lost on the second day of training camp.

Initially, he was concerned, too. His phone blew up. But, tests revealed it was only a dislocated toe on his right foot.

“God was looking out that day,” Fields said Tuesday, in his first comments since what turned out to be a minor injury.

For the next few weeks, Fields will wear a protective plastic shield on the outside of his cleats to protect the toe.

It didn’t seem to hinder him in practice. He used his legs on a few occasions, as he practiced fully.

The toe, Fields said, is “working its way back to 100 percent.”

Fields missed only one practice, important considering he is on a new team with a new coaching staff.

“Now is the moment to accumulate those repetitions,” Fields remarked. “Implementing new plays, making it crucial to use this period for practice. It’s key for aligning with your team members, particularly when you’re adopting new strategies and concepts.”

“So, definitely, I didn’t want to miss much time, and that’s why I was so eager to get back on the field and wanting to keep going.”

The Jets are bringing back a familiar face.

The team signed veteran kicker Nick Folk on Tuesday to solidify a position that has looked shaky early in training camp.

Folk, 40, had a significant stint with the Jets from 2010 to 2016, delivering essential field goals, most notably the decisive 32-yard kick that led to their victory against the Colts in the 2010 AFC wild-card playoff.

Chuck Vine, a close friend and adviser to Folk, shared this statement with The Post from Folk: “Rejoining the Jets is incredibly meaningful. This organization has been instrumental in my career and is full of wonderful memories. Yet, I’m here with a focus on competing, guiding the team, and performing my duties at an elite standard.”

“He is a very established kicker in this league,” head coach Aaron Glenn said. “When you go back and you look at his stats from the last couple of years, they’ve been above board. … I’m happy that he chose us to be a part of what we’re trying to do.

The Jets began training camp with rookies Caden Davis and Harrison Mevis on the roster.

Both have been unimpressive in camp.

The team waived Davis on Tuesday to make room for Folk, who only missed one field goal attempt in each of the past two seasons for Tennessee.

He went 21-for-22 last year and 29-for-30 in 2023 with the Titans.

Mike Westhoff, a special teams coaching guru who spent 2001-12 with the Jets, attended practice.
