How Brock Purdy helped Brandon Allen from 49ers’ sideline vs. Packers

Quarterback Brock Purdy couldn't play in the 49ers' 38-10 loss to the Green Bay Packers on Sunday due to a shoulder injury.

But that didn't stop him from doing what he could on the sideline to help his temporary replacement -- San Francisco backup Brandon Allen.

After the game, Allen praised Purdy's assistance as another set of eyes in between drives.

"[Purdy] was great," Allen told reporters. "He asked how I was seeing it, what he was seeing. Some of the rotation stuff they had going on and how he was seeing it. Ideas of where to get the ball. But he was really helpful on the sideline for me."

Though the 49ers' blowout loss doesn't inspire much confidence moving forward, Allen put together a solid performance for a backup quarterback given the circumstances. With left tackle Trent Williams inactive, Allen went 17 for 19 for 199 yards and a touchdown to tight end George Kittle.

Allen did throw an interception, though one could argue it wasn't really his fault because the throw deflected off the hands of receiver Deebo Samuel. Allen also fumbled once while being sacked in the second half.

Still -- especially given San Francisco's nine penalties for 77 yards -- it's hard to expect more from a backup quarterback making his first regular-season start in three years. And given Allen's comments, Purdy's advice could have played a significant role in that solid showing.
