According to Chris Balas (citing EdgyTim.com, the Rival's Illinois prep site):
As you all likely know, he was supposed to be at the game this weekend, but could not make it for unstated reasons. This is definitely a good sign though (in my opinion) for us because
1. He's not visiting anywhere else for a while so our cancellation is not unique.
2. He's makin his trip an official visit (it was supposed to be an unofficial visit before), which likely removes one competitor for his services and shows that despite Ann Arbor's geographic convenience, it's worth using one of his officials to go to Michigan (for about the 200th time).
