If the Dr or manager told Timber to play through it, then it's obviously their fault. Timber is also a big boy and if he said it's all good to the Dr., then it's possibly his fault. We don't know, so it's dumb to point the finger at somebody without having all the facts just because you need an effigy to burn.
Either way, would be terrible news if he's out and the way he pulled up looked ominous. Season ending kind of ominous.
