Labuschagne was handed a three-match ban by World Rugby on Friday after receiving a red card for a dangerous tackle in Japan’s 35-12 loss to Fiji last week but will have his sanction reduced to two games if he takes part in a Coaching Intervention Programme.
World Rugby’s independent judicial committee found the offence met the threshold for a six-match suspension but said there were mitigating circumstances and reduced his ban by half.
Those circumstances have not been revealed as the full judgement has not been published.
Labuschagne, who made his international debut in 2019, is the second Japanese player to be suspended in the last month. Captain and number eight Michael Leitch received an effective two-match ban following a red card against Samoa, but will be free to face Chile.
