The 49ers' latest historic feat is one they won't be proud of.
San Francisco, with its 20-17 loss to the Seattle Seahawks on Sunday at Levi's Stadium, tied a long-standing NFL record.
The 49ers now have three NFC West divisional losses this season after leading in the final two minutes of regulation, tying the 2001 Carolina Panthers, 2000 Los Angeles Chargers, 1996 Baltimore Ravens and 1994 Washington Commanders for the most in a season since the 1970 merger, according to the Elias Sports Bureau.

San Francisco led Seattle 17-13 with 2:00 remaining on Sunday before Seahawks quarterback Geno Smith executed a game-winning touchdown drive.
In Week 5, the 49ers led the Arizona Cardinals 23-21 at the two-minute mark before quarterback Kyler Murray led Arizona's offense down the field for a go-ahead field goal.
In Week 3, San Francisco led the Los Angeles Rams 24-17 with 2:00 remaining before a Matthew Stafford-led drive ended in a Kyren Williams game-tying rushing touchdown and an eventual go-ahead field goal two drives later.
Because of those late-game collapses, the 49ers now have a 1-3 NFC West division record and, at best, would split the season series with all three of their division rivals if they were to win their Week 15 and Week 18 matchups against the Rams and Cardinals, respectively.
