Graeme Swann has been penalised for "showing serious dissent" during his comeback game for Nottinghamshire against Durham in the County Championship this week.
The ECB confirmed that the England spinner had been found guilty of a level two breach - but escaped a ban.
Swann was given out lbw, bringing to an end Nottinghamshire's second innings.
He remained at the crease with his hands above his heads, before walking off.
An ECB statement read: "During Nottinghamshire's LV= County Championship match against Durham on 29 April-2 May 2013, Swann was reported by umpires Steve Garratt and Peter Willey for a level two breach of the code (showing serious dissent at an Umpire's decision by word or action)," an ECB statement read.
"The penalty for this offence is three penalty points which will remain on his record for a period of two years. The accumulation of nine or more penalty points in any two year period will result in an automatic suspension."
Swann made his return from elbow surgery in the Trent Bridge match, taking 4-56 in the second innings as Durham chased down a victory target of 183 in 20.2 overs.
