Aaron Rodgers showcased flashes of his MVP form after leading the Green Bay Packers to a thrilling 30-28 victory at the previously unbeaten San Francisco 49ers.

The Packers were facing their second defeat of the season after Jimmy Garoppolo's 12-yard touchdown pass to Kyle Juszczyk gave the 49ers a 28-27 lead with 37 seconds remaining on Sunday.

But some last-drive heroics from Green Bay superstar Rodgers – without a timeout left – lifted the Packers (2-1) as Mason Crosby's game-ending 51-yard field goal condemned the 49ers (2-1) to their first loss of the season.

Rodgers finished 23-of-33 passing for 261 yards and two touchdowns without an interception, while team-mate Devante Adams also starred with 132 yards and a TD on 12 receptions.

Three-time MVP Rodgers also surpassed Hall of Famer Dan Marino (51,741) for the fourth most passing yards in a player's first 200 games in NFL history. Drew Brees, Matt Ryan and Peyton Manning are the only players with more passing yards through 200 appearances.

In eight regular-season games versus the Niners heading into this matchup, Rodgers had thrown 18 touchdowns to only two interceptions, and owned a passer rating of 106.9 – the highest against San Francisco in the Super Bowl era (minimum 100 attempts).

The 49ers rallied at home to the Packers, overcoming early 10-0 and 17-0 deficits before falling behind 24-14 at the start of the final quarter.

Trey Sermon's one-yard run and the Juszczyk-Garoppolo combination during the closing stages had the 49ers on the cusp of a third straight win and a completed comeback, however, the Packers still had enough time to snatch a last-gasp victory.

Garoppolo finished 25-for-40 passing with 257 yards, a pair of touchdowns, one interception and four sacks.
