Vitalini, 27, has scored five tries in 14 appearances for the Scorpions this season, and bolsters the All Golds squad ahead of the play-offs.
He said: “I’m really pleased to be signing with the All Golds for the rest of the season.
“I wasn’t looking to leave the Scorpions but when Steve McCormack approached my coach Mike Grady and I was given Mike’s blessing to leave the Scorpions if I wanted, then it was just an opportunity that I couldn’t refuse.
“The chance to play in the play-offs doesn’t come around all that often and I hope that I can make a big contribution towards making that happen. I would like to thank all the staff, players and fans at the Scorpions for their support in what has been a difficult year and I hope that they can understand my decision. I’m looking forward to getting stuck straight in with the All Golds, starting with the game this weekend against the Skolars and hopefully we can have a big go and make a statement in the play-offs.”
The All Golds have targeted a top five finish and Steve McCormack is confident that this addition will help the club to make this a reality.
He said: “It’s great to have Chris back on board at the All Golds for the remainder of the season.
“We are well aware of what Chris will bring to our side and it is a timely addition to have in the challenge to make a play-off spot. I’d like to thank Mike Grady and the South Wales Scorpions for allowing Chris to come to the All Golds.”
