49ers' Brock Purdy: Officially clears protocol

Purdy cleared the NFL's concussion protocol Saturday and has no injury designation ahead of Sunday's game against the Bengals, Tom Pelissero of NFL Network reports.

Though Purdy was initially listed as questionable for the Week 8 contest following a full practice Friday, he had his designation removed after he was able to pass through the last of the five steps of the concussion protocol Saturday, when he was cleared by an independent neurologist. Since Purdy was also able to take part in non-contact portions of Thursday's practice, he should be well-versed in the 49ers' game plan for Week 8, despite having sat out Wednesday's practice session after entering the protocol following Monday's loss to the Vikings. Purdy may be operating without two key pieces on offense, however, as top wideout Deebo Samuel (shoulder) will miss a second straight game Sunday, and standout left tackle Trent Williams (ankle) is listed as questionable and uncertain to play.
