The reigning NFC champions faced a puzzling loss on Sunday.
The San Francisco 49ers lost to the Minnesota Vikings 23-17 as star running back Christian McCaffrey missed his second straight game. In his absence, backup running back Jordan Mason stepped up for another solid game with 100 rushing yards and a touchdown.
Quarterback Brocky Pudry put together a decent game with 319 passing yards, a touchdown and an interception, but it wasn't enough to get past the Vikings.
Minnesota didn't seem like the biggest threat to take down the 49ers coming into Sunday's matchup, but the Vikings pulled off the upset and left San Francisco fans frustrated on social media.
