Somehow Iowa's Jordan Lomax was not ejected for this nasty hit on Illinois receiver Geronimo Allison. It looked kind of dirty and that he led with the crown of his helmet. The refs didn't even throw a flag so they weren't going to review it either, but maybe they should have thrown the flag so a review would have been triggered.

Whether it was legal or not though, Lomax laid some serious wood on Allison and he clearly felt it as you can tell by the reaction from him.
