In Week 2 and Week 3 Kansas City Chiefs DE Shaun Smith was accused by Cleveland Browns C Alex Mack and San Francisco 49ers RT Anthony Davis of grabbing them below the belt. There were no penalty flags on either play though video exists of the alleged Week 3 incident and, while it does suggest that there is some grabbing going on, there isn't a clear angle of it.
And via Twitter Smith writes today:
It's going to be a good day because I won my appeal so am 10000 richer again
The league doesn't comment on appeals so we'll have to take his word for it.
