Injury plagued All Blacks and Chiefs midfielder Richard Kahui has suffered another shoulder injury putting his Super Rugby season in doubt.
Kahui missed the start of the Super Rugby season but has become a regular starter until last week when a hamstring strain kept him out of the match against the Sharks.
The midfielder suffered the hamstring injury playing against the Waratahs in Sydney the week before.
Kahui's latest injury occurred in training during a tackling session at the Chiefs Ruakura training base and caused to become a spectator at Tuesday's training.
"It's not very good," Chiefs coach Dave Rennie told Fairfax NZ News.
"The issue is around his shoulder now. His hammy is OK but the medics are referring him to have another scan because he's got pain in his shoulder - the one that was operated on (last year)."
Rennie said that Kahui's latest shoulder injury during a tackling session on Sunday.
"It felt sore and then he threw out a hand to catch a ball and he felt a little pop in there."
Kahui's playing career has been plagued with injury and he has already had six shoulder operations.
Last year he was sidelined for 10 months after dislocated his shoulder playing Super Rugby in May against the Reds in Brisbane.
Kahui missed all of the Rugby Championship, the All Blacks end of year tour and only returned on March the 22nd when he came off the bench against the Highlanders.
The 2013 Super Rugby season could be Kahui's last as he has signed a two-year contract with Japanese club Toshiba and will leave New Zealand after the Super Rugby season.
