Dolphins Blatantly Ignore HC Jeff Hafley’s Strict Warning as Multiple Fights Break Out at Giants Joint Practice

“If you throw a punch, you’re gone.” That was HC Jeff Hafley’s standard before the Miami Dolphins shared the field with the Giants at Baptist Health Training Complex in Miami Gardens. With roster jobs, preseason reps and the regular season all approaching, Hafley challenged Miami to show toughness the way it matters in football: absorb the shove, return to the huddle and win the next legal snap. Joint practices test that discipline as much as they test a team’s talent, but the Dolphins were about to test just how firmly their new head coach intended to enforce it.

Per videos circulating on social media, at least two fights broke out during the joint practice between the Dolphins and the Giants.

“First a minor tiff on one field, then a full-on skirmish on the other as Dolphins and Giants get chippy,” wrote Fox Sports’ Greg Auman on X. “Jameis Winston hurries into the scrum for a shove and got pulled out by multiple defensive linemen. Giants assistant knocked to the ground trying to break it up.”

In one of the videos circulating online, Dolphins’ offensive tackle Austin Jackson can be seen throwing a punch at a Giants player. Giants’ defensive end Kayvon Thibodeaux, in turn, grabbed Jackson and threw him down on the ground as both teams gathered around. True to his word, Hafley immediately pulled Jackson from team drills.

Jackson’s altercation was not the first sign that the workout was getting out of hand. During an earlier offensive line-defensive line period, Giants edge rusher Abdul Carter threw a punch at Dolphins left tackle Patrick Paul after the two got tangled at the end of a rep. The incident drew a flag and helped set an uneasy tone for the rest of the morning.

The Giants’ pass rush had also created sustained pressure before the confrontations escalated. Brian Burns beat Jackson during one-on-one drills, while Carter later recorded a sack against him in the final 11-on-11 period. The on-field advantage does not prove why tempers flared, but it was part of the competitive backdrop to a tense two-plus-hour session.

The practice was not defined by a single flare-up. A separate scrum involving the Giants’ offense and Miami’s defense took nearly a minute to clear, with Jameis Winston repeatedly moving toward the pile before defensive linemen pulled him away. A Giants assistant was knocked to the ground while attempting to help separate players.

Ahead of their joint practice with the New York Giants at the Baptist Health Training Complex in Miami Gardens, a reporter asked him, “What’s the message to your team today so that it doesn’t turn into a melee?” Hafley’s response was both a warning and a statement of the culture he wants in South Florida.

“It’s the same thing that I say every day to the team. That’s not tough,” Hafley noted. “Like anybody who’s been around me and watched us play, I want to toe the line, and I want to play physical, and I want to be tough. But fighting’s not tough. And I told him, if you’re frustrated with a guy and you get pushed or shoved, tell him, ‘I’ll see you next play.’ And then go play the next play and do it again. That’s tough. That’s mentally tough, right?

“Because in a game, what’s going to happen when you get frustrated? You’re going to get thrown out of a game. If you throw a punch, you’re gone, especially now with the new rules, you’re going to be able to see it. It’s not part of the game. So, I’ll be really disappointed. If a guy throws a punch, he’s out. We haven’t had that happen in our practice much. And the other thing is, I told him, I think there’s a brotherhood in the NFL. You got to respect that all these guys right now, these 180 players, they’re all trying to earn a job. And there should be mutual respect about the guys in this league on how hard they’re working to get a job.

“You’re being evaluated by both staffs today, right? And you want to try to fight and hurt a guy on the other team? I’ve seen it, I get it, it gets chippy. It’s going to be hot out there. But if you want to find out who’s really tough, find the guy who walks back to the huddle, lines up and goes at it next play. I will be really, really, disappointed. Could it happen? Sure. I will be very disappointed and it will be addressed immediately if it happens.”

Even Giants head coach John Harbaugh had noted hours before the practice that he’d spoken with Jeff Hafley to establish strict guidelines to keep both teams’ players safe. These rules included not making any “blindside shots” to their quarterbacks or anyone else.

“We’ll have rules of engagement, we’ll call it,” Harbaugh said, per SB Nation’s Ed Valentine. “Talked to Coach Hafley. He talks to his team. We talk to our team. We have the same rules of engagement.”

But something like that is very hard to put into practice. Fights like these have become commonplace at the training camp as the 2026 NFL season draws ever closer. Just days before, the Dallas Cowboys also got into seven different fights during their joint practice with the New Orleans Saints.

Dallas’ outside linebacker Donovan Ezeiruaku was ejected from the practice for throwing a punch. Cornerback Caelen Carson also got into a scuffle with Saints wide receiver Brock Rechsteiner; Cowboys safety Jalen Thompson intervened by tackling Rechsteiner, but the rookie wide receiver responded by delivering a suplex on Thompson.

As for the Dolphins, Hafley had already delivered a similar warning a week before, ahead of their joint practice with the Washington Commanders. “We don’t have time for that,” Hafley had said, noting that the team’s focus should be on playing physical. The Dolphins lost their first preseason game against them 20-7. Tempers were already flying high after that, and practice with the Giants is where it all boiled over.

The first-time NFL head coach needs his team to channel this energy on the gridiron when they face the Giants for their second preseason game this weekend. Surprisingly, this isn’t the first time he’s laid the same rules down.

Jeff Hafley’s rule did pass its first test.

While it didn’t work out today, Hafley had made the same point eight days earlier, before Miami traveled to Ashburn, Virginia, for its first joint practice of camp against the Washington Commanders. Asked whether he expected the session to get chippy, the first-year Dolphins coach gave his players a simple boundary:

“If there’s a punch thrown, they’re out.”

The Commanders workout offered the kind of controlled competition Hafley wanted. Dolphins edge rusher Chop Robinson repeatedly tested Washington right tackle Josh Conerly Jr. in one-on-one and team drills, breaking into the Commanders’ backfield and emerging as one of Miami’s most productive players of the session. Washington’s defense, meanwhile, pressured Miami’s offense, while quarterback Jayden Daniels led an efficient day for the hosts.

Miami went on to lose the preseason opener to Washington 20-7 two days later, but the joint practice itself did not produce the multi-player skirmishes that would follow against the Giants. That made Hafley’s pre-Giants warning less a reaction to a previous meltdown than a repeated expectation: compete hard, but do not let a practice rep become a fight.

The preseason results won’t hurt or help their 2026 campaign. But if the teams cannot keep their tempers in check on game day, both sides risk serious injury that could derail their regular season long before September arrives.
