Robert Snodgrass will not face disciplinary action for his criticism of referee Mark Clattenburg on Twitter following Norwich's 2-1 defeat to West Ham.
Clattenburg awarded a second-minute penalty to West Ham for shirt-pulling by Ryan Bennett on Winston Reid during the New Year's Day clash, a decision Snodgrass did not agree with.
The midfielder tweeted: "The referee kills the game. If that's a pen you will need to give 100 pens a season, small decisions change games."
The FA confirmed there will be no action against Snodgrass, their social media rules state action may be taken for "comments about match officials which imply bias, attack the officials' integrity or which are personally offensive in nature".
