Bristol Bears captain Steven Luatua suffered a dislocated wrist as his side were beaten 38-29 at home by Harlequins on Sunday, director of rugby Pat Lam confirmed post-match.
The former All Black flanker, making his first start in three weeks having been nursing a calf injury and coming off the bench, left the field in the 10th minute with his shirt turned into a makeshift sling.
His departure came moments after he scored a wonder-try in the corner to drag his side back into the contest at Ashton Gate having gone 14-0 down inside the first five minutes.
