The last thing the San Francisco 49ers needed for their Week 12 matchup with the Green Bay Packers was to be without their starting quarterback, but it appears they may have to deal with that scenario.

Brock Purdy left practice on Thursday after throwing just a few passes in the section of the session open to media.

According to Matt Maiocco of NBC Sports Bay Area, Purdy was seen getting his shoulder rubbed by head athletic trainer Dustin Little before the quarterback left prior to the start of practice.

Purdy has been dealing with shoulder soreness in the wake of the 49ers' surprise loss to the Seattle Seahawks last Sunday, one which left them 5-5 and bottom of the NFC West.

He was officially listed as limited for Thursday's session, but the 49ers' decision to push the usual quarterback media session back to Friday suggested there is a strong chance Purdy will not play at Lambeau Field.

If that proves to be the case, Brandon Allen would get the start under center for the 49ers. Joshua Dobbs is the third-stringer.

Nick Bosa and Trent Williams again missed practice, while reigning Offensive Player of the Year Christian McCaffrey was back after a rest day on Wednesday.

Rookie wide receiver Jacob Cowing sat out the session after being limited on Wednesday, indicating he is on course to miss the game with a concussion suffered against Seattle.
