As far as Springer goes I hope they are just being cautious and that it's not a setback. If he's not 100% give him another week if he needs no sense in rushing it and risking re-injury.
But I don't like the sound of this. It sounded like he was playing full intrasquad games last week. Then they were talking about him playing this past weekend, then DH'ing today, and then all the sudden he's not ready. It just doesn't vibe but hopefully it's nothing.
