“All business” Chris Brooks is the Packers’ latest signing this season.

GREEN BAY — It was Josh Jacobs’ show for much of the Packers’ 30-27 win over Jacksonville last Sunday.

The former All-Pro running back tore through the Jaguars defense en route to 127 yards on 25 carries. Jacobs broke tackles, pushed for piledrivers and scored two touchdowns while battling an ankle injury he suffered earlier in the contest.

Finally, after a 3-yard run to the Jaguars’ 12-yard line with a minute remaining, the Green Bay coaching staff called Jacobs to the sideline and called Chris Brooks to finish the job.

It was the ultimate sign of confidence in the backup running back, who started the regular season on the practice squad before earning a call-up to the 53-man roster in Week 3.

Brooks did what was asked, completing the Rolex play to perfection and going down after a 9-yard run to the Jaguars’ 3. That allowed Green Bay to run down the clock and send kicker Brandon McManus for the game-winning 24 points. – a field goal in the yard after time expires.

“He’s a selfless person,” Jacobs said. “He plays on special teams. He is involved in everything. Can’t say enough good things about a guy like this who is willing to put his body on the line. He has a lot of respect in this dressing room.”

Brooks, 24, is the latest in a series of key season-long acquisitions the Packers have made in recent years, especially along the backfield.

In 2012, DuJuan Harris came out of nowhere to lead the Packers into the playoffs. Six years later, Tyler Ervin was signed away from Houston to assist Matt LaFleur’s offense during his first season as head coach and offensive lineman.

Like Harris and Ervin, Brooks’ first stop in the NFL wasn’t Green Bay. He split his college career between Cal and BYU before signing with Miami as a college free agent last year. He scored his first 53 points as a member of the Dolphins and played in nine games as a rookie, gaining 106 yards on 19 carries.

The 6-foot-1, 219-pound running back’s bid to re-enter Miami’s lineup was derailed when he suffered a concussion during the Dolphins’ second preseason game. He signed with Green Bay’s practice squad after reaching an injury deal with Miami and made his first impression on Packers coaches.

“He’s the epitome of a professional,” offensive coordinator Adam Stenavich said. “Everything he does is very intentional. I don’t know if I’ve ever seen him laugh or smile in all the time he’s been here. It’s just business, a serious guy, and that’s great. He’s hungry, he wants to make a name for himself and I think every week he goes out he gets better and a little better.”

Brooks also had a known admirer in Packers linebackers coach and running game coordinator Anthony Campanile, who shared the sideline with Brooks last year in Miami.

Whenever his linebackers battled the Dolphins’ running backs in periods, Campanile knew his guys were in for a good job when Brooks lined up on the other side.

“I think he’s a really good player. He’s a great person,” Campanile said. “Any time you have a great guy in your locker room, you’re excited about that (guy) bringing the right things. He’s a competitive guy. I think it has a lot of advantages. He’s a fierce runner. I think he’s good. Defensively, I think he’s a complete player and a team guy.”
