The Rugby Football League have found Terry Newton guilty of striking and handed the Bradford hooker a two game ban.
The Great Britain international, 28, was also handed a fine of £500 at the hearing in Leeds on Tuesday.
There had been calls for a lengthy ban after his late tackle on Jon Wilkin in the Saints-Bradford match at the weekend.
The ex-Wigan player was banned for 11 matches of last season for dangerous tackles, also against Saints.
Wakefield prop Danny Sculthorpe, put on report in the Wildcats game at Hull, has also been told he faces no further action.
