Terlich, 23, was rushed to hospital by ambulance after the sickening incident at Moorabbin Oval.
The Demons revealed through their official website that Terlich would undergo tests as a precautionary measure, following the collision.
He remained conscious throughout the entire incident and scans later cleared the defender of any damage, according to afl.com.au.
Terlich, who was drafted from Norwood in the SANFL, joined the Demons through last year's draft with selection 68 overall.
