Is Brock Purdy Playing in Week 13?

After missing Week 12 due to a right shoulder injury, Purdy was limited in practice Wednesday and Thursday before a full session on Friday. He was declared questionable on the final injury report, but head coach Kyle Shanahan said he expected his starting QB to return.

Purdy was also limited for last week’s Wednesday session. He went limited again last Thursday before being downgraded and ruled out on Friday.

Purdy’s upward trajectory at practice this week was a great sign. The clearest sign of his return arrived on Friday, when he threw at practice and backup quarterback Brandon Allen occupied a scout team role.

Allen completed 17 of 29 attempts for 199 yards, one touchdown, and one interception vs. Green Bay. He earned a C (72.8) in PFN’s QB+ grades, No. 19 among 26 quarterbacks who played in Week 12.

Should You Start or Sit Brock Purdy in Week 13?

Brock Purdy (right shoulder) sat out last week against the Packers. Advanced testing showed no structural damage, leading to cautious optimism that he’ll return to the lineup this week. Should that be the case, I think there’s a possibility Purdy gives us a borderline QB1 performance.

The Bills excel at shutting down opponents from big perimeter plays, but this 49ers offense is happy to focus on the shorter passing game and let their athletes work in space.

Purdy has completed 71.9% of his passes since Christian McCaffrey returned to the field, and I don’t think that’s an accident. He has a quartet of top-six finishes this season, thanks in part to four rushing scores over his past four games.

No, he’s not Lamar Jackson. He’s not even Daniel Jones when it comes to athleticism, but Purdy is mobile enough to raise his fantasy floor, which I think will help this week against a patient Buffalo defense.

If we get a clean bill of health entering the weekend, Purdy will move inside of my top 15 quarterbacks.
