Scotland lock Gilchrist suspended for rest of Six Nations after red card
Gilchrist was sent off after seven minutes following direct shoulder contact with Anthony Jelonch's face after referee Nika Amashukeli saw a "high degree of danger" in the move.
Since Gilchrist admitted committing an act of foul play warranting a red card before the hearing and "expressed remorse", the standard six-week suspension was reduced to three.
Gilchrist will miss Scotland's final two Six Nations games against Ireland (March 12) and Italy (March 18).
He is also set to be suspended for Edinburgh's game against Connacht in the United Rugby Championship later this month but can avoid sitting out if he completes a tackle course.
"The player applied to take part in the Coaching Intervention Programme to substitute the final match of his sanction for a Coaching Intervention, which was granted by the Committee," it said.
"The programme is aimed at modifying specific techniques and technical issues that contributed to the foul play."
Scotland are second in the Six Nations championship after three rounds, five points behind unbeaten leaders Ireland.
