49ers' Kyle Juszczyk: Limited at practice

Juszczyk (concussion) was a limited participant at practice Thursday, Matt Barrows of The Athletic reports.

Juszczyk was unable to practice to open the week Wednesday, so his return to action Thursday is a step in the right direction. The fullback remains in concussion protocol, and he'll likely have to log a full practice Friday in order to have a chance to play Sunday against the Cardinals.
