If Nick Herbig was staging a minicamp “hold-in,” there’s no need anymore.

The 24-year-old edge rusher and the Pittsburgh Steelers agreed to a four-year, $100 million extension Tuesday, according to NFL Network and ESPN. Herbig didn’t use the term “hold in” to describe his first day of mandatory minicamp, but he was wearing a ballcap and merely observing when the outside linebackers ran their individual drills.

Asked after practice if his desire was to get an extension from the Steelers in lieu of hitting the open market next spring, Herbig said: “It’s my desire to be a Steeler for life.”

Within a few hours, they had locked him in through the 2030 season.

The 6-foot-2, 240-pound outside linebacker is entering his fourth season with the Steelers. He made a career-high 7 1/2 sacks last season, upping his career total to 16. But he has done so largely as a backup, playing a complementary role to starters T.J. Watt and Alex Highsmith.

Herbig is believed to be the first non-quarterback to receive a $100-million extension without ever starting an entire NFL season, according to ESPN’s Adam Schefter.

“I wouldn’t call myself not a starter,” said Herbig, who made six starts last season. “I would just say I’m a team guy. If you need me to play off the ball, on the ball, need me to run down on punt, like, I’m a Steeler. There are no starters and backups. I’m a Steeler.”

The team has allocated a significant amount of money to the edge rusher position. Highsmith is playing on a four-year, $68 million extension that runs through 2027. Watt signed a three-year, $123 million extension last summer that locked him up through 2028.

Finding new ways to use Herbig is a job for defensive coordinator Patrick Graham.

“We have been doing that,” coach Mike McCarthy said. “I think if you watch the early team period, the pressure drill has been outstanding. … It’s great to have Nick here. Nick’s excited about being here, and so we’ll definitely highlight the packages for Nick, both this week and next week.”

The mandatory minicamp continues Wednesday. The team has organized team activities remaining on June 8, 9, 11 and 12. The practice-like OTAs are voluntary. Herbig was asked if he had sought advice from Watt, who has “held in” and “held out” at different points in his Steelers career.

“Yeah, I mean, business is business,” said Herbig, due to make $3.84 million in the final year of his rookie contract. “I’m a football player. I’m here for football. I try to keep business separated from football as much as I can.”

Herbig wasn’t spotted at earlier OTA sessions open to the media or included in photographs posted on the Steelers’ website. But McCarthy said Herbig was in “constant communication” in recent weeks.

In fact, the two ate lunch together in March in Scottsdale, Ariz.

“It was an awesome time,” Herbig said. “Just the fact that he took the time out of his busy schedule to invite me to have lunch with him meant the world to me. He’s a Pittsburgh guy, so I’m just excited for him, as he is for me, that he gets this opportunity to coach his hometown team, and, you know, bring us to another Super Bowl.”
