If Thursday delivered a gut punch for the Jets, a reminder about the fragility of a season that briefly sucked the life out of training camp when an offensive lineman stepped on Justin Fields’ right foot and dislocated a toe, then Friday gave them plenty of tangible reasons for a sigh of relief.

There was Fields jogging over to the stands and signing autographs before the session. There was the quarterback — the one handed a two-year, $40 million deal and labeled the starter — stretching without any noticeable limp, just as he would at any other point during the year.

Fields kept his helmet on throughout individual and team drills, too, and while he didn’t participate in anything beyond the stretching, the Jets could extinguish lingering worries from what head coach Aaron Glenn described as a “huge storm” that “really made no sense.”

“I would rather have a guy that I have to hold back than have to tell him to giddy up,” Glenn said.

Fields remains day-to-day, Glenn said, and the Jets now will be tasked with navigating the delicate balance of not rushing him back — it still is the first week of camp, after all — and trying to maximize all possible reps before Gang Green start their season Sept. 7 against the Steelers.

But any fear of a serious, long-term injury stemming from the scene Thursday, when Fields hobbled and exited in the front seat of a cart, was replaced by the promising sign of him being at least present one day later.

“It meant a lot to us,” backup quarterback Tyrod Taylor said. “Obviously, him being on the field brings good energy to the team. … He’s one of our leaders, and obviously him not being hurt for a long time was obviously good news, as well. Seeing him energized and back on the field, ready to compete, I’m sure he would’ve went today if it was up to him. That’s the competitor that he is.”

All of the backup plans can get filed away for the time being. This won’t be Aaron Rodgers 2.0 or another instance when the Jets needed to pivot on the fly.

There won’t be a need for them to prove they actually have a dependable backup quarterback this time, and unlike when Rodgers went down in 2023, with Taylor and his 94 career games and his 58 career starts oozing with stability. Fields will need to quell any concerns by seamlessly meshing back into Gang Green’s offense, but for one day, at least, everything seemed as close to normal as possible.

It’s still unclear when Fields will return to practice, and Taylor, as he did at the end of Thursday’s session, took the first-team reps. But Glenn expected Fields to be pushing for a quick return, as his presence on the field certainly seemed to suggest, once they got the diagnosis. That’s just who Fields is. “He’s built like that,” Glenn said.

But even with the injury impacting his toe, Fields’ mobility won’t be limited, Glenn said. He will need to serve as a focal point of a Jets offense expected to feature a strong rushing attack, given his 2,509 rushing yards and 19 touchdowns across four seasons.

“If Justin gets back to practice, that means he’s ready to go,’ Glenn said. “So, he’s gonna be himself and I’m not going to hold him back from being himself.”

Until then, Fields will continue to sit in on meetings. He will continue to observe a quarterback room that now features a mix of experience in Taylor (a 14-year veteran) and inexperience with Brady Cook and Adrian Martinez (zero regular-season snaps) during periods at camp.

But at some point, Fields will inherit the offense again. The first hint emerged Thursday, with the team-issued medical update noting he avoided a significant absence. One day later, with fans packed into the Atlantic Health Training Center complex on a blistering day for the first open practice of the summer, Fields, by simply being there, gave them a reason to relax.

“Just his presence,” left guard John Simpson said, “it means a lot.”
