Canberra have bolstered their attacking potency by signing Storm star Curtis Scott on a four-year deal after Melbourne released the centre as well as halfback Brodie Croft on Friday.
Scott will join the Raiders' pre-season training in early December after he was granted a release from the final two years of his contract.
Croft was contracted to the Storm until the end of next season but has been allowed to leave the club and is expected to front at Broncos training on Monday although Brisbane are yet to officially announce his signing.
Scott, 22, will join a star-studded Canberra backline featuring Jarrod Croker, Jack Wighton, Nick Cotric and Joey Leilua.
However, the 48-gamer's arrival will raise further questions about the future of Leilua, who is off contract next year and could head elsewhere.
"Curtis is a player we believe has a very big future in the game and we're thrilled to have him join us for the next four seasons," Raiders high-performance director Peter Mulholland said.
"At just 22 he's already been able to play almost 50 NRL games and he's an exciting talent who will give our squad a player who is hungry to further his development and become an even better player."
Croft, who made his debut in 2016, played 39 games for Melbourne but lost his position as first-choice halfback late in the season to Jahrome Hughes.
It is understood Brisbane view him as an ideal senior halves partner to young gun Tom Dearden.
The Broncos will need to release a player from their 30-man squad to accommodate Croft's arrival and NRL.com has been told Gehamat Shibasaki could switch to Newcastle although neither club has made an official statement on that possibility.
