The San Francisco 49ers are entering Week 3 with cautious optimism at the quarterback spot. Brock Purdy, with injury concerns, took part in practice this week, and although he wasn’t a full go, the latest update suggests he’s trending in the right direction.
Backup Mac Jones remains ready to go should Purdy be unable to start or finish. Purdy’s participation in practice reps has been encouraging: he’s moving better, taking snaps, and rejoining portions of the team drills several sources report.
Mac Jones continues to stay sharp. While the expectation remains that Purdy will be under center, Jones’ presence provides the team with insurance. If Purdy’s timing, mobility, or ability to push the ball downfield are compromised due to his injuries, Jones can step in without the 49ers having to alter too drastically from their offensive identity.
Here’s what to keep an eye on with Purdy's status heading into the weekend:
What’s encouraging:
What could go wrong:
If Purdy can play at even 80-90 percent, the 49ers have a strong chance to continue their winning ways. But if he is limited enough to risk turnovers or bottle up the offense, then Mac Jones may need to carry the torch for another week. Either way, the 49ers can get it done this weekend, it’s just going to be a matter of how easily.
