Wasps have signed former Australia scrum-half Brett Sheehan on a deal until the end of the season.
Sheehan arrives in the Premiership from Western Force as a replacement for Jack Moates, whose knee ligament injury will keep him out until next season.
The deal means a first overseas move for the 34-year-old, who won the last of his seven Wallabies caps in 2012.
He told the Wasps website: "Having played all of my club rugby in Australia, it is great for me to be able to go overseas and experience a different league and a different brand of rugby.
"Since the move was suggested to me, I have been impressed with what Dai Young and his team are doing at Wasps.
"The young players they have at the club are very exciting and I hope that I can impart a bit of my experience during my time there. I can't wait to get going."
Director of rugby Young said: "We have been operating with only two first-team scrum halves in recent weeks, which clearly isn't enough - to be able to bring in someone with the experience that Brett has is brilliant.
"We have two talented young scrum halves here in Joe Simpson and Charlie Davies so Brett brings a great balance to that group.
"I have no doubt that his experience will be a benefit for those two, as well as Jack Moates as he continues his recovery from injury."
