Following the bye-week, despite a continuing knee injury, Rodgers had his third consecutive week with a 100+ quarterback rating, which included 286 yards passing, no interceptions, and a go-ahead 40-yard touchdown pass to Marquez Valdes-Scantling in a 29–27 loss to the Los Angeles Rams.

In Week 13 against the Atlanta Falcons, Rodgers set an NFL record by converting his 359th consecutive pass without an interception, breaking Tom Brady's previous record.

On December 18, 2018, Rodgers was named to his seventh Pro Bowl.
He declined the appearance due to injury and was replaced by Russell Wilson.

In the regular season finale against the Detroit Lions, Rodgers suffered a concussion early in the game and would not return.
He was then sent to the hospital to test for concussion symptoms.
Because the Packers had already been eliminated from playoff contention, Rodgers answered questions about whether he should be playing, for fear of injury, by saying: "That's just not the way I lead, and I'm super-competitive, and I want to be out there with the guys and I look forward to being out there."
Rodgers was later spotted at the Packers' facility after the game.

Rodgers finished the season with 372 completions, 597 attempts, 4,442 passing yards, 25 passing touchdowns, two interceptions and a passer rating of 97.6.
His touchdown to interception ratio of 25:2 (12.5) ranks third best all-time (min 300 attempts).
In addition to setting the record for consecutive passes without an interception during the season, Rodgers set NFL records for interception percentage for a season, with only 0.335% of his passes being intercepted, and for the amount of thrown away passes.
He was ranked ninth by his fellow players on the NFL Top 100 Players of 2019.
