Norwich midfielder Robert Snodgrass will not face disciplinary action for his criticism of referee Mark Clattenburg on Twitter.
Clattenburg awarded a second-minute penalty to West Ham, who went on to win 2-1 against the Canaries at Upton Park on Tuesday, for shirt-pulling by Ryan Bennett on Winston Reid.
Snodgrass, 25, later tweeted: "The referee kills the game. If that's a pen you will need to give 100 pens a season, small decisions change games."
