In addition, Marist's Ritchie Campbell and Pirates' Lasa Ulukuta were also sent warning letters by the WRFU for receiving their second yellow cards.
Kenny said the punishments should be a warning to players on the sidelines against getting involved and escalating on-field incidents.
The two Pirates will miss today's game at Spriggens Park against Harvey Round Motors Ratana, as will Ratana winger Onewa Tai who has a two-game suspension for being sent off against Utiku Old Boys.
After a week's break, the return of Tasman Tanning Premier and Senior rugby saw two red cards and 12 yellow cards handed out across the grades.
