From rotoworld, Nelson Cruz and Jhonny Peralta will accept suspensions. (Referencing tweets by Bob Nightengale and Ken Rosenthal, resp.) Not a surprise in Peralta's case, somewhat surprising for Cruz.
Ken Rosenthal has a pretty full list on his twitter feed. Accepting 50-game suspensions are Cruz, Peralta, Bastardo, Valdespin, Everth Cabrera. "Also suspended" (accepting the suspension?) are Cervelli, Montero, Puello, Escalona, De Los Santos, Martinez, Norberto. Not facing any new discipline are Colon, Grandal, Melky. No violations found for Gio and Danny Valencia.
