Phillies catching prospect Tommy Joseph is back on the disabled list with an all too familiar ailment.

Joseph has been placed on the 7-day disabled list with concussion-like symptoms.

Joseph missed most of the 2013 season with a severe concussion he sustained when a foul ball hit him in the mask.

Joseph had been playing well at Reading this season.

Reading outfield prospect Kelly Dugan was also placed on the 7-day disabled list with a strained oblique.
