Southland prop Jamie Macintosh and Waikato prop Ben Tameifuna will face Judicial hearings Tuesday, after separate incidents in their Week Four NPC Cup match in Invercargill.
Southland won the match 20-16.
Mackintosh was cited for an alleged stamping, a breach of law 10.4(b), on Waikato reserve back Sam Christie, eight minutes from full-time.
Tameifuna was cited for the same alleged offence, on Southland's Mackintosh in the 50th minute of the match.
Both players will appear separately before judicial officer Chris Morris, by video conference, on Tuesday.
