The Hurricanes have today confirmed Beauden Barrett will sit out four weeks of the Investec Super Rugby competition.

Barrett's scans revealed a grade two tear of his medial collateral ligament (MCL) which he suffered during the Hurricanes' match against the Crusaders on Saturday, May 2.

"Obviously I'm gutted with the injury, but fortunately it's not season ending for me," said Barrett.

"I've been pretty lucky to have a good run without injury for a while, but it's now up to me to work hard on my rehab and make sure I'm ready to return at the business end of the season."

Should all go well with his rehabilitation, the Hurricanes are hopeful Barrett will be available for selection when the Hurricanes face the Crusaders in Nelson on May 29.

Hurricanes management have called back Manawatu's Otere Black from New Zealand Under-20 duty, and he will remain with the team for the next three weeks.
