Glasgow out-half Adam Hastings has been handed a three-match ban following his red card in Sunday's defeat to Leinster at the RDS.
The Scotland fly-half was found guilty of "reckless or dangerous play" after raising his foot while catching a high ball and making contact with Leinster wing Cian Kelleher’s face.
"The incident was found to merit a mid-range entry point, which indicates a six-week suspension for this offence," said Guinness Pro14 organisers.
"The Judicial Officer determined that there were mitigating factors, including the player’s acceptance of the foul play, immediate and genuine remorse, cooperation with the disciplinary proceedings and clear disciplinary record, which under the disciplinary rules warranted a reduction in the sanction of 50 percent.
"The player is suspended from participating in the next three meaningful matches."
The suspension rules Hastings out of consideration for Scotland's Six Nations game against Ireland, although the former Bath player was not included in the squad for either of the Scots' opening two matches.
