ADELAIDE draftee midfielder Ned McHenry will be monitored for concussion after being involved in a car accident on Friday.

McHenry, pick 16 in last year's NAB AFL Draft, had initially suffered a concussion last weekend playing in the SANFL.

He had recovered and been cleared to play this weekend but has concussion symptoms and neck pain after the back of his car was run in to.

"Unfortunately, Ned was rear-ended in a motor vehicle accident on the way home after completing a session where he trained very well," Adelaide science and medical services coordinator Steve Saunders told afc.com.au. 

"He has now reported neck and concussion symptoms. This is obviously disappointing given how well he had recovered. 

"Ned is not available to play this weekend and will continue to be monitored closely by the medical team."
