They've already sent out promotional tweets that include Parekh (or his jersey/locker plate) in plan view. I don't think they plan on suspending him for the prospects game.
I also want to preface this with the fact that this is not an accusation but, what if someone said something that made Parekh react the way he did? Like yeah he's a bit of dick sometimes but I doubt he's spitting on people for the heck of it. Refs don't hear anything but see Parekh spit. Kick him out. If no ref heard anything, you can't go back and do something on hearsay. Maybe they call it a wash and nothing comes of it? I still think it'll be a couple games after Wednesday but we'll see.
