Dragons lock forward Rynard Landman has had his appeal against a six-week suspension for use of an elbow dismissed by a disciplinary committee.
The South African was sent off a quarter of an hour into their loss to Connacht,
At the initial hearing before an independent Disciplinary Committee, the player received a six-week suspension, which was set to end on Sunday, April 19.
But the Dragons captain then chose to appeal the decision, which was unsuccessful, as a PRO12 Rugby statement explained on Wednesday.
"The player's appeal was based on two grounds, confined to the question of sanction (i.e. that the Disciplinary Committee had erred in determining that the offending warranted a top end entry point of nine weeks and again in reducing the entry point suspension by just three weeks to take account of mitigating factors)," it read.
"The Appeal Committee, having received submissions on behalf of the player and the PRO12 Rugby Disciplinary Officer, both in advance of and at the hearing, dismissed the appeal in its entirety. The Appeal Committee found that the Disciplinary Committee had not made the errors that the player had alleged. The player's suspension remains as it was originally imposed.
"The Appeal Committee ordered the player to pay the costs of convening the hearing and the legal costs incurred by the Disciplinary Officer in responding to the appeal."
