I called the league to see if they had an idea about whether Adrian Wilson's hit on Matt Hasselbeck was an offense warranting a fine. I have not heard back from them.
Just to add perspective, when there was a question of whether Leroy Hill would be fined for his big hit in Tampa Bay, the league responded almost immediately, saying that Hill's hit was legal and he would not be fined.
Not sure if that means anything, or if it means they are looking at Wilson's hit more closely since he was fined earlier this season. But if the league gets back to me, I'll post it.
