Marlins' Chad Wallach: Set for further evaluation

Wallach (concussion) paused his rehab assignment for further evaluation Monday, Andre Fernandez of The Athletic reports.

Wallach has been battling a concussion since late May. He's made a pair of brief rehab appearances, the latest lasting just a single game. Given the difficult nature of head injuries, it's tough to say when Wallach is expected to return to the field.
