What happened to Austin Collie in the Indy vs. Eagles game?

It was an unintentional helmet-to-helmet hit from an Eagles defender. It wasn't a vicious hit but Collie took it in a bad spot. The way the NFL is now this will probably draw a suspension even though it wasn't a dirty hit. Hopefully Collie's okay. They weren't taking any chances (and shouldn't) so it might have looked worse than it really is.
