Pearsall (illness/chest) doesn't have an injury designation for Sunday's game against the Cardinals, Nick Wagoner of ESPN.com reports.
Coming off a Week 17 breakout performance, Pearsall should have a featured role in the San Francisco offense Sunday with fellow wide receiver Deebo Samuel (ribs/wrist) ruled out. QB Brock Purdy (elbow) also is out, however, leaving Pearsall and Jauan Jennings to catch passes from backup Joshua Dobbs.
