JACKSONVILLE, Fla. >> The Green Bay Packers might have to play without quarterback Jordan Love again.

This time, it could be longer.

Love injured his left groin on the opening possession against Jacksonville, left the game for good in the third quarter and then had a front-row seat as backup Malik Willis rallied the Packers to a 30-27 victory.

Coach Matt LaFleur said he had a “high level of concern” for Love’s latest injury. Love missed two games in September with a sprained left knee.

With Love watching from the sideline Sunday, Willis completed a 51-yard pass to Jayden Reed that set up Brandon McManus’ second winning kick in as many weeks. Willis completed 4 of 5 passes for 56 yards, with a touchdown and the biggest completion of the day.

“The moment’s never too big for him and he made a lot of big-time plays in this game, not only with his arm,” LaFleur said.

Willis found Reed wide open down the left sideline after safety Andre Cisco cramped up and fell down.

“I already knew I was going to be open before the play was even called,” Reed said.

It was all the Packers (6-2) needed to rebound from Trevor Lawrence’s perfectly placed, 14-yard touchdown pass to Evan Engram that helped tie the game.

Engram caught the ball between three defenders and gave the Jaguars (2-6) all the momentum. But LaFleur dialed up a gut-punch on second down that was the difference.

Jacksonville tried to let the Packers score, but Chris Brooks dropped to the ground to help set up McManus’ 24-yarder.

Josh Jacobs ran for 127 yards and two touchdowns for Green Bay, including a 38-yard run in which he juked defenders Ventrell Miller and De’Antre Prince.

“He’s a stud isn’t he?” LaFleur said. “The physicality that he runs with. ... He is a pro’s pro. I can’t say enough great things about him.”

Lawrence completed 21 of 32 passes for 308 yards.
