Sisa Waqa

Waqa, who was a member of Melbourne's 2012 premiership-winning team, will take the number of Fijians in the NRL to 23 if he can convince Storm coaching Craig Bellamy to sign him after a stint with French rugby union club, FC Grenoble.

The 31-year-old recently returned to Melbourne, where his family had been living, after breaking his jaw and was offered a training contract with the Storm.

Melbourne football director Frank Ponissi said a decision would be made on whether to sign Waqa before June 30 so he is eligible to play the remainder of the season.

Waqa will remain part of the Raiders NRL squad until his release and will continue to train and play with the squad.

Waqa said the decision to move to French Rugby was a tough one and said he remained committed to the Raiders until his release is finalised.

"The Raiders have been great for my career and my family and it has been a hard decision for me to make," Waqa said.
