Kiwis rugby league star Corey Harawira-Naera is under investigation by the NRL integrity unit, after being pulled over for drink-driving on Christmas Eve.
When tested by police, the Canberra Raiders forward returned high-level alcohol readings, reports Fox Sport.
"The Canberra Raiders can confirm that both Corey Harawira-Naera and Corey Horsburgh were involved in separate incidents during the Christmas holiday period," his club confirms.
"Both incidents were reported directly to the NRL integrity unit at the time and the club continues to keep them informed of any developments.
"As both issues are still pending court matters, the club will not be making further comment."
Horsburgh is also believed to have returned a low-range alcohol test on January 3.
Last March, Harawira-Naera, 25, and teammate Jayden Okafor were stood down by Canterbury Bulldogs, after they brought two schoolgirls back to their hotel room during a pre-season trip to Port Macquarie.
The incident cost the Bulldogs a major sponsor, and Auckland-born Harawira-Naera had his contract terminated and was deregistered by the NRL. After a successful appeal, he asked the club for a release and subsequently signed a two-and-a-half year contract with the Raiders.
