Marshawn Lynch wasn't the only Seahawks player fined on Thursday. His teammate wide receiver Chris Matthews also received a penalty from the NFL -- and Lynch wasn't happy about it.
In a tweet, Marshawn said he was "embarrassed to work for a particular organization that fined a teammate of mine for shaking my hand after a touchdown."
However, his teammate's fine wasn't for the handshake according to USA TODAY Sport's Tom Pelissero. Matthews was fined for a crotch grab -- the same action Lynch himself was fined for.
Lynch was fined $20,000 for making the inappropriate gesture after his touchdown in the NFC Championship on Sunday and $11,050 for the same gesture earlier this season.
