The St George Illawarra Dragons have granted requests from forwards Tyrone McCarthy and Mose Masoe to be released from their current playing contracts to take up opportunities in England.
McCarthy played two NRL games during his two seasons at the Dragons, and not only captained the Illawarra side to Intrust Super Premiership and NRL State Championship success in 2016 but was also a member of the club's leadership group.
"Tyrone's been a very good club player for us and he was offered a contract to head back to the UK. We agreed that it was in his best interests to take up the longer-term deal," Millward said.
"So that means Tyrone will leave us and he'll go back to the Super League for the remainder of the year and beyond."
Masoe will also take up an opportunity overseas pending he receives the necessary clearance and registration to make the move to the United Kingdom.
While a season-ending ACL injury ruined Masoe's first season at the club last year, the 28-year-old Samoan international has featured prominently for Illawarra in 2017.
"Mose needs to get a visa but there's also a certain amount of games he must play and different criteria's related to playing football in England," Millward said.
"Mose's injury last year meant he hasn't been in a position to accumulate the games required – meaning if he doesn't leave now then he won't be able to qualify to play in the UK in 2018.
"He came and asked for an immediate release on compassionate grounds due to the offer in England, which would present him the opportunity to secure a contract for his family long-term."
Meanwhile, Millward said that winger Kalifa Faifai Loa has requested a release from the remainder of his Dragons contract and has also been given permission to negotiate a move overseas.
However the 26-year-old veteran is yet to sign a contract with another club and will remain at the Red V until he signs elsewhere.
"Kalifa's situation is very similar to Mose - he hasn't quite played the amount of games to play in the UK in 2018. However he's played an adequate enough games to secure a contract and a visa for the remainder of the season in the UK," Millward said.
"He's come to us seeking a release but at the moment he hasn't agreed to a deal with anyone. He has a couple of clubs interested and we've given him permission to go and negotiate with other clubs.
"If he finds another club then he will leave in the coming weeks."
Masoe and McCarthy's departures follow the early releases of Chris Lewis and Shaun Nona late last month.
