McCaffrey (Achilles) is not present at the portion of Friday's practice open to the media, Nick Wagoner of ESPN.com reports.
McCaffrey logged limited sessions Wednesday and Thursday, but it appears his activity level may be in line to regress Friday. 49ers GM John Lynch said Friday morning that he was uncertain whether McCaffrey would be cleared to suit up Sunday against Minnesota on the road, and head coach Kyle Shanahan will address the media later this afternoon. Jordan Mason enjoyed a breakout performance Week 1 with McCaffrey sidelined, while wide receiver Deebo Samuel also was tasked to handle extra backfield slack and logged eight carries.
