He came back in later in the game after it showed him ripping the O a new one. I don't know how much he came back for but he was back in the game. Last report I heard was a separated shoulder which would have been why he couldn't lift his arm above his head.
I thought He slipped as well. He seemed to fall as he wanted to turn upfield.
I don't know what calls you saw going our way but the refs seemed to be trying to help Dallas pull through. The usual holds on Hali. The D Holding call on Berry at the end of the game was a joke that nullified his pick. The PI on Dez was maybe questionable but whenever the receiver gets both hands on the shoulder pads of a Dback it is going to get called. I also think he got away with pulling Flowers down on his first catch any way so it worked out a bit.
The announcers couldn't even get it right. Dontario? Really? They called Kendrick Lewis Eric Berry more than once. They had no idea most of our Defenses name and just resorted to calling them the "KC Defenders" They won't get any love being a small market team and that's cool but if your going to announce on National TV, at least get the players names right, you owe them that much.
