The player is ruled out for South Africa's autumn internationals.
South Africa prop Jan-Hendrik Wessels has received a ban of nine games for touching Josh Murphy's private parts during the Bulls' URC victory over Connacht.
The altercation happened in the early stages of the narrow victory against Connacht on last Friday, with Connacht forward Murphy receiving a 20-minute red card after reacting angrily by striking Wessels on the head area.
After Murphy reported the incident to referee Mike Adamson, the contact was reviewed by the television match official, who found no conclusive video evidence.
The Bulls player remained on the field until he was substituted in the later stages of the match.
While the United Rugby Championship announced that the Irish player's temporary sending-off was overturned by a disciplinary panel, Wessels was deemed to have violated the code of conduct, which declares:
"A player must not do anything that is contrary to the spirit of good sportsmanship. Such behavior covers grabbing, pulling or compressing the genitals."
Disciplinary officials were satisfied that the event reached the level for dismissal and warranted a 12-week suspension, the shortest suspension under World Rugby rules for such an offence.
Nonetheless, Wessels' suspension was reduced by three weeks because of his cooperative behavior during the proceedings and his good record.
The forward and the Bulls are entitled to appeal, but currently, the suspension will prevent the 24-year-old out of the Springboks' autumn Tests against the Brave Blossoms, France, Italy and Ireland.
He will also miss the Bulls' league matches against Glasgow, the Lions and the Sharks, as well as European cup fixtures with Bègles and Northampton.
The prop has earned ten international appearances for the Springboks and was part of their Rugby Championship-winning squad during the recent tournament.
The Connacht player, in contrast, is available to face Munster in this weekend's domestic clash after being exonerated.
