Keibert Ruiz Injury: Still having concussion symptoms

Ruiz has been pulled off his rehab assignment with Double-A Harrisburg on Monday due to mild headaches and will rejoin the Nationals in Miami to re-enter concussion protocol, Mark Zuckerman of MASNSports.com reports.

Ruiz's return from the 7-day injured list had seemed imminent, but interim manager Miguel Cairo was non-committal on the 27-year-old's availability to play again this season following his latest setback, per Spencer Nusbaum of The Washington Post. Riley Adams will continue serving as the Nationals' primary catcher while Ruiz is shelved, with Jorge Alfaro backing up Adams.
