James O'Connor has been summoned to face a French rugby disciplinary hearing this month over his alleged cocaine possession.
The former Wallabies back is to front the Ligue Nationale de Rugby's discipline and rules commission on March 29, along with co-accused Ali Williams, an ex-All Black.
O'Connor was suspended for a match by his club Toulon after his arrest and charge over cocaine possession last month, missing last week's Top 14 clash against Brive.
His future at Toulon remains unknown with his non-selection in this weekend's Top 14 home clash with Bayonne on Saturday (Sunday AEDT).
He was due to meet with club owner Mourad Boudjellal this week.

New Zealander Williams faces the more serious charge with purchasing the cocaine, apologising after being suspended by French club Racing 92.
He is expected to face a Paris court.
The 44-Test player O'Connor was fined for possession of the drug for his involvement in the incident.
Racing 92 president Jacky Lorenzetti says Williams will be sacked by the Top 14 club after his arrest.
Lorenzetti told Midi Olympique magazine that "unfortunately, Ali Williams will soon be dismissed."
Lorenzetti added that Williams tested negative for cocaine after his arrest.
