Sydney - Reds playmaker Quade Cooper's hopes of playing in the Super Rugby playoff against the Sharks on Saturday hinge on a judiciary hearing on Monday.
The Wallaby flyhalf was sin-binned by referee Steve Walsh and later cited for a high tackle that forced Waratahs counterpart Berrick Barnes to be replaced in the defending champions' 32-16 win in Brisbane on Saturday.
SANZAR on Sunday said Cooper would face a hearing on Monday.
A SANZAR statement said Cooper was alleged to have tackled Barnes in the 63rd minute of the match, making contact above the shoulders.
Cooper was one of the Reds' outstanding players in the five tries to two win over the Waratahs to claim the Australia conference and the third ranking playoff spot ahead of the Brumbies, who surprisingly lost to the Blues at home.
