Samu Kerevi admits the Queensland Reds have discipline issues after captain Scott Higginbotham was banned for three weeks, while Lukhan Tui is also in the sights of the Super Rugby judiciary.
Higginbotham was red‑carded after just nine minutes in Friday's defeat to the Melbourne Rebels for an "objectively dangerous" shoulder charge on Matt Phillip.
He will miss the next three Reds games ‑ against the Brumbies and Bulls at home, and then away to the Jaguares in Argentina.
Meanwhile, Tui has been summoned to front a SANZAAR hearing on Tuesday night and could face a similar suspension after he was yellow‑carded for a lifting tackle on Wallabies halfback Will Genia in the first half against the Rebels.
The Reds were constantly hampered by sin‑binnings and send‑offs in 2017.
