Worst night ever mare as Brock Purdy announced his departure Today from the 49ers another significant issues for….

Brock Purdy went from MVP favorite to 49ers concern in three quarters.

Purdy threw four interceptions in a 33-19 loss to the Ravens on Christmas night and left the game with his second stinger in as many weeks.

San Francisco coach Kyle Shanahan was optimistic that the injury would not force Purdy to miss any time as the 11-4 49ers try to hold on to the top seed in the NFC.

“He stayed in there, kept battling,” Shanahan told reporters after the game. “Our whole team struggled there in the second half, so it wasn’t just him.

“I know he was disappointed not being able to finish it there, but given that stinger again, I just wanted to keep him out of there. Ready for him to bounce back next week.”

Purdy was replaced in the fourth quarter by Sam Darnold, who threw a touchdown pass with San Francisco futilely trying to rally late.
