Frolik said Wednesday, "It was like he toe-picked a little bit and I just fell right on him. I thought at first it was really, really bad. I don't know what his status is now. I talked to our doctors and they said he was little better than they expected, so hopefully that's a good sign and hopefully he is going to be OK. It [stinks] when those things happen."
