The Rebels' 2019 attrition is continuing, with David Horwitz signing a deal with Irish club, Connacht.

Horwitz moved to Melbourne ahead of the 2018 season, but has been shuffled down the pecking order behind players like Billy Meakes, Reece Hodge and Tom English in the centres, yet to play a game for the Rebels.

The 23-year-old joins James Hanson, Jono Lance and Nic Stirzaker among a list of names who have left the Rebels or signalled their intent to move overseas, with the club needing to contract for the 2019 season.

Horwitz said he was looking forward to the move overseas.

“I am really excited about my move to Connacht," he said.

"I have enjoyed my time in Super Rugby and would like to thank the Rebels and their fans for my time there.

"Connacht are really ambitious about their plans for the future and I share that ambition and hope to contribute to bringing further success to the province.

"I am looking forward to focusing more on my favoured position of out-half with Connacht and joining my future team mates at the end of the current Super Rugby season.”

Connacht CEO Willie Ruane said Horwitz would be a handy addition.

"We are excited to announce the signing of out-half David Horwitz from the Rebels. David is a quality out-half who has also built up considerable experience at centre.

"His Super Rugby credentials are obvious having featured heavily for the Waratahs last season. He will be another strong addition to Connacht and we look forward to his arrival next season.”

Horwitz follows Brumbies centre Kyle Godwin to the Irish club, which also counts Aussie Jarrad Butler among its numbers.
