The San Francisco 49ers added Brock Purdy to the injury report on Wednesday for a shoulder issue. The star quarterback has been dealing with soreness in his right (throwing) shoulder since the 49ers 20-17 loss to the Seattle Seahawks on Sunday.

Purdy was limited in Wednesday’s practice but did not throw a pass. On Thursday, the third-year quarterback threw passes but exited practice early to work on rehabilitating the injury.

Head coach Kyle Shanahan said on Thursday that he was hopeful that Purdy could play against the Green Bay Packers on Sunday. The 5-5 49ers are set to travel to play the 7-3 Packers at Lambeau Field on Sunday.

Per Friday’s injury report, San Francisco ruled out Purdy for Sunday’s contest against the Packers. The 49ers announced on social media Friday afternoon they plan to start Brandon Allen.

The Jacksonville Jaguars selected Allen in the sixth round of the 2016 draft. The native of Fayetteville played college football for the Arkansas Razorbacks.

Allen is 2-7 as a starter in the league. The 32-year-old has gone 149-of-263 passing for 1,611 yards, 10 touchdowns and six interceptions in his five-year NFL career.

Allen last made his start for the Cincinnati Bengals in 2021 against the Baltimore Ravens. The Ravens defeated the Bengals 38-3 in a game that Allen went 6-of-21 for 48 yards and two interceptions.

Allen has attempted no passes for the 49ers this season.
