Ali Williams about to be sacked by Racing

The former All Blacks lock Ali Williams is about to be sacked by his French club Racing 92 after being charged with purchasing cocaine.

"Unfortunately, he will soon be fired," club president.Jacky Lorenzetti told rugby weekly Midi Olympique.

AAP reports the 35-year-old Williams was charged last month.

Former Wallabies winger James O'Connor, who plays for Toulon, was also arrested and charged with possession.

Both players have been stood down by their clubs.

Williams, a 77 test veteran, has been summoned to appear at the National Rugby League's discipline commission on 29 March.

He is alleged to have purchased $300 worth of cocaine.

Earlier this month Williams apologised on social media saying "I made a big mistake and I'm sorry. I feel I've let down our beloved rugby community. I will face the consequences. Thanks 4 all the support."

Williams is reportedly seeking a plea bargain with police and is yet to appear in court on the drugs charge.
