GREEN BAY, Wis. — When the Green Bay Packers and Arizona Cardinals step onto the practice field Wednesday, the spotlight will fall on a familiar surname. For the first time as head coaches, Matt LaFleur and his younger brother Mike LaFleur will direct their teams against each other, turning a routine joint practice into a family affair.

Matt, the Packers' 46-year-old head coach, couldn't resist injecting humor into the situation. Speaking Monday, he joked about how he would prevent scuffles from breaking out during the session. "If there's an issue, I'm going to tell the guys, 'Hey, you come tag me in. They can tag in my brother. And we'll throw down on the 50,'" he said with a grin. The remark highlighted the playful dynamic between the siblings, who are separated by seven years in age but share a deep bond forged in the NFL coaching ranks.

Mike, 39, was hired as Arizona's head coach this offseason after stints as offensive coordinator with the New York Jets (2021-22) and Los Angeles Rams (2023-25). The joint practice at Green Bay marks the first time the brothers have squared off as head coaches, though they have been on opposing sidelines before. In 2021, when Mike was with the Jets, their teams held joint practices in the same city. Now, with both holding the top job, the stakes feel different, yet the tone remains lighthearted.

Matt was asked about their parents' allegiances during the week. "They'll probably look like a Christmas tree — green and red," he said, referencing the Packers' green and gold versus the Cardinals' red and white. The comment drew laughs, but behind the banter lies a genuine sense of trust. Both coaches admit that working with a brother offers advantages when it comes to sharing information and setting ground rules.

Mike, however, insisted that the decision to practice in Green Bay was not driven by family ties. He simply wanted to escape the scorching Arizona heat. "If we could have gone to Seattle to go against them, that would be great," he said. "Well, they're in our division, so we're not going to Seattle. There's no team in Canada yet. And you'd rather not go all the way out to Buffalo, just from a travel standpoint. So you think about that next closest team to get you out of the heat, it really is Green Bay." He also mentioned reaching out to the Minnesota Vikings after his hiring, but they already had joint practices scheduled. The opportunity to work in a town with such rich football tradition, he added, is something he appreciates. The Cardinals plan to embrace the local culture by riding bicycles from their locker room to the practice field, accompanied by children, just as the Packers do each day during training camp. "There's a ton of fans there," Mike said. "I mean, it's Green Bay. What else are you going to do?"

Both LaFleurs highlighted the value of trust in these joint sessions. Matt recalled that when the Packers practiced with Houston in 2019, they were careful about what they showed because the Texans' staff included John Pagano, brother of then-Chicago Bears defensive coordinator Chuck Pagano. "But I think when it comes to this situation, I don't have any hesitation or reservations," Matt said. The family connection also ensures that both teams deliver consistent warnings about conduct, especially after the NFL fined the Dallas Cowboys and New Orleans Saints $500,000 each last week following a series of brawls in their joint practice.

Mike emphasized the importance of sending the same message to both teams. "Let's call it what it is. These joint practices, flip a coin on what could happen sometimes. Obviously we know the ramifications now, what the league can do as well. I do think that will change some people's opinions on what the code of conduct should be," he said. "It's been good. We're on the same page with how we're going to conduct this thing." When asked about his older brother's challenge to settle disputes at midfield, Mike quipped, "We'll see what happens."

In other Packers news, Matt LaFleur said defensive tackle Warren Brinson will "miss a little bit of time" after tweaking his calf during pregame warmups Friday, which kept him out of the game against Denver. Rookie second-round cornerback Brandon Cisse, who left the Broncos game with a knee issue, practiced Monday and appears to be recovering. The brothers will reunite again Friday for a preseason game at Lambeau Field, adding another chapter to their unique coaching rivalry.
