The Giants brought back two of their own just two days before the start of NFL free agency.

Punter Jamie Gillan and tight end Chris Manhertz — who have spent a combined 15 seasons in the NFL — both re-signed with the Giants on Saturday, The Post confirmed.

Gillan, 27, signed a three-year contract worth up to $10.2 million with incentives, per NFL Network. It includes $4 million guaranteed, ESPN reported. The max value ranks No. 7 among punters and his $3 average annual salary ranks No. 4.

Nicknamed “The Scottish Hammer,” Gillan has been the punter for the entire Joe Schoen-Brian Daboll era, after he was on the Bills practice squad when both of those decision-makers were in Buffalo.

He averaged a career-low 43.7 yards per punt, but with a career-best 48.2 percent of his boots inside the 20-yard line last season.

It appears that the Giants are set to run it back for a fourth straight season with the same three core special-teamers: Long-snapper Casey Kreiter, kicker Graham Gano and Gillan, who doubles as Gano’s holder.

There had been speculation that the once-automatic Gano would become a salary cap casualty to save $3.6 million after two straight injury-plagued down years.

Manhertz, 32, has made a 10-year career out of blocking like a sixth offensive lineman.

He has 29 catches in 137 career games, including three (with a touchdown) for the Giants last season.

A good complement to a receiver-first tight end, Manhertz will be paired again with Theo Johnson, whose rookie 29-catch season was cut short. by surgery to repair a Lisfranc injury to his foot

Former starter Daniel Bellinger lost snaps to both Johnson and Manhertz last season and will be on his walk year in 2025.

The Giants decided not to punt on Jamie Gillan.

Two days before the start of free agency, the Giants re-signed their veteran punter, The Post confirmed.

It’s a three-year contract worth up to $10.2 million with incentives, according to NFL Network.

The exact structure of Gillan’s deal is not known, but it ranks as the seventh-highest among NFL punters in terms of max value.

It includes $4 million guaranteed, per ESPN.

Nicknamed “The Scottish Hammer,” Gillan, 27, has been the punter for the entire Joe Schoen-Brian Daboll era after he was on the Bills practice squad when both of those decision makers were in Buffalo.

He averaged a career-low 43.7 yards per punt, but with a career-best 48.2 percent of his boots inside the 20-yard line last season.

Gillan’s previous contract, signed after the 2022 season, was a two-year, $4 million deal. The Giants decided not to mess with the chemistry of their kicking operation.

It appears the Giants are set to run it back for a fourth season with the same three core special-teamers.

Long snapper Casey Kreiter re-signed a one-year deal last week, and kicker Graham Gano remains on the roster despite speculation that he could become a salary cap casualty (to save $3.6 million) since his once-automatic performance has nose-dived over the past two seasons.

Gillan doubles as the holder for Gano.

Other top punters who are scheduled to hit the market when free agency begins Monday include the Commanders’ Tress Way, Cowboys’ Brian Anger, Panthers’ Johnny Hekker, Chargers’ JK Scott and Bills’ Sam Martin.
