A SANZAR Judicial Hearing has found that Brumbies wing Henry Speight contravened Law 10.4 (j) Lifting Tackle, after he was sent off on Saturday.
The incident took place during the qualifying final against the Stormers at Newlands.
However, a SANZAR statement read: "Further information has been requested for consideration by the Judicial Officer before a sanction can be determined."
"No comment from any party will be made until the hearing is complete."
The Brumbies go to Wellington this week for a semi-final with the Hurricanes, but look set to do so without Speight.
