New York Yankees outfielder Clint Frazier (head) is dealing with post-concussion migraines and was placed on the 10-day disabled list. Frazier has dealt with head injuries off and on this year, so the Yankees will be extremely careful with their outfield prospect. It's a shame, since he was a trade candidate given how crowded the Yankees outfield has been this year. There is no timetable for his return. You should probably only keep Frazier stashed in dynasty leagues.
