The other player fined, according to Barrows, was Seahawks defensive lineman Jarran Reed for his hit on 49ers quarterback Nick Mullens. His hit carried a heftier $20,054 fine.
As Barrows points out, there is no word on whether or not head coach Kyle Shanahan will be fined for his in-game use of a colorful metaphor toward an official after Wilson threw 49ers linebacker Fred Warner's shoe.
Update: Shanahan was fined $25,000 for his sideline outburst.
