This isn't Donaldson's "calf issues." Bux gets himself injured in a myriad of ways. Crashing into walls, ok those are legit. But once you've had a concussion, they tend to reoccur much easier. But let's face it, that man is accident prone. Hit by pitches because he awkwardly tries to avoid them. Sliding into bases. Eating a steak. Sure, rest him throughout the year so he's healthy for the playoffs, only to slip in the shower and break an arm...
I said it in the other thread, nobody can control what happens. Someone way wiser than me once said "tomorrow isn't guaranteed."
