James Segeyaro will join the Sharks as soon as this week and the talented hooker is expected to be named later today in coach Shane Flanagan's 21-man squad to play the Eels.
After being granted permission to officially train with the club late last week, Segeyaro has been provided with a release from UK Super League club the Leeds Rhinos and once his new contract has been registered by the NRL will be eligible to turn out for the Sharks.
The new contract with the Sharks will be for the 2017 and 2018 seasons.
"I'm excited to have him in my squad," Sharks coach Shane Flanagan said.
"James has missed a fair bit of training and we probably won't see the best of him for a few weeks however he is a quality player and one that will certainly add something to our team.
"He gives us some real competition at hooker and Jayden (Brailey) will need some help during the year and James will provide that."
