London Wasps centre Lee Thomas has been ruled out for the remainder of the season with a ruptured Achilles tendon.
The 28-year-old Welshman was forced off five minutes from the end of Wasps' 30-23 defeat at Exeter on Saturday.
Director of rugby Dai Young told the club's website: "We are bitterly disappointed to lose Lee who was really starting to find his feet in a Wasps shirt.
"I thought he was excellent against Leicester and played very well against Exeter until he was forced off and it's a big blow to lose him for so long."
Thomas joined Wasps from French club Lyon in March.
