Newcastle Falcons centre Juan Pablo Socino has been banned for two weeks for striking Exeter counterpart Ian Whitten in Saturday’s Premiership loss.
Socino, 29, was sin-binned for the incident in the match and, after being cited, attended a disciplinary panel on Wednesday.
He will miss two European games against Newport-Gwent Dragons and Bordeaux Begles before returning on 24 October.
“The panel found this was a reckless act,” panel chair Antony Davies said.
“[One] in which the player made contact with the opposition player’s jaw with his forearm.”
The Argentine’s previous good record and character saw his ban reduced by the panel.
