How do you rehab a concussion?

Cervelli played a rehab game but only DHed?



I'm confused how you rehab a concussion and why you would only bat in doing so?   Concussions must be alot different than they used to be with respect to symptoms.

He hasn't faced live pitching in 2 weeks. Looks like they just want to shake off the rust for a couple games before he rejoins the Bucs.
