San Francisco 49ers quarterback Mark Purdy’s 42.6 passer rating was his worst as the 49ers’ starter during their Christmas Day loss to the Baltimore Ravens.

In addition to four interceptions, he finished 18-of-32 for 255 yards as the Grinch stole their win.

“The first (interception) was a big mistake, and the other three were pretty unfortunate,” head coach Kyle Shanahan said.

This meeting was billed as a showdown between the NFL’s two leading MVP candidates – Purdy and Ravens quarterback Lamar Jackson, the latter of whom threw for 252 yards and two touchdowns while rushing for 46 yards.

The 49ers (11-4) remain in position for the NFC’s No. 1 playoff seed, and they still can lock that up by winning their final two regular-season games – Sunday at the Commanders (4-11), and Week 18 against the Los Angeles Rams (8-7). The 49ers currently own the tiebreaker advantage over the NFC’s other two teams with 11-4 records, the Detroit Lions and the Philadelphia Eagles.

“It’s easy to be riding high and thinking you’re the man, when things are going well, you’re winning games, and you don’t see a whole lot of adversity in some games. This is the reality of the NFL,” Purdy said.
