49ers Brock Purdy in concussion protocol

Darnold is the 49ers backup quarterback and Shanahan said that the team has full confidence in him if Purdy is unable to play. The 49ers are still hopeful that Purdy can clear protocol by the game.

Shanahan even said that Purdy wouldnt necessarily have to practice to be able to play Sunday, pointing at last seasons Thursday night win at the Seattle Seahawks, when Purdy played with a broken rib after not having thrown a ball at practice that week. David Lombardi, 49ers writer

Shanahan said Purdy felt better Wednesday than he did the previous day and would even be permitted to be on the field for the walk-through portions of Wednesdays practice. That has the team optimistic he might be able to clear the concussion protocol and be able to play against the Bengals in Sundays game. Also encouraging is the way Purdy played in Seattle last season. He suffered a rib injury in the game before that one and the 49ers played the Seahawks on a short week.

Not only did Purdy not practice in full, but he hardly threw the ball in the run-up to the contest. Still, he was mentally sharp for the game, completing 17-of-26 passes for 217 yards with two touchdowns and no interceptions. Matt Barrows, 49ers writer
