LESLEY VAINIKOLO has undergone surgery to repair his ruptured right Achilles tendon and will not play again this season.
The Gloucester and England winger underwent surgery from specialist James Calder at the Cromwell Hospital in London on Monday night and will be out of action for at least seven months.
The 29-year-old suffered the injury during the first-half of Gloucester's 22-16 Guinness Premiership victory over Saracens on Saturday, having just helped create a score for full-back Olly Morgan.
Vainikolo has made 17 appearances in all competitions this season and has scored eight tries. In 35 appearances since his debut against Leeds Carnegie last season, when he scored five tries, he has scored 19 times in 35 appearances and has made five appearances for England following his debut against Wales in the Six Nations last season.
"Les is a massive part of our squad, not just for his on-field contributions but because his personality is such an integral and vital part of the group," said Gloucester's head coach Dean Ryan.
"It will naturally leave a very significant gap and with the current injuries we have in the squad at the moment this could not have come at a worse time.
"Les has undergone surgery and when it is appropriate he will begin his rehabilitation process but we appreciate it will be a long road and he will have all the support he needs from everyone associated with the club."
