Jamayne Isaako is expected to head to Parramatta after being granted an early release from his Brisbane NRL contact.
The 25-year-old fullback has signed with the Dolphins from next season, but will leave the Broncos immediately after the club confirmed his departure on Tuesday morning.
"The Broncos have granted Jamayne Isaako an immediate release from his contract with the club," a club statement read.
"The Broncos were happy to facilitate the request and wish Jamayne and his young family all the best in the future, both on and off the field."
It has been speculated Isaako will join the Eels for the remainder of the season before starting his contract at the NRL's new Redcliffe-based club.
Isaako has made 77 appearances for the Broncos, scoring 24 tries.
He started Brisbane's round one win against South Sydney at fullback before Tesi Niu took over in the No.1 jersey in round two.
