The 23 year-old is one of many new high profiled signings at the KC Stadium with Hull FC wanting to improve on their inconsistent season in 2015.
Fonua was a tryscorer on his debut in his side’s opening game victory over Salford Red Devils last weekend, but was injured in the act of scoring after collecting a high ball.
There were worries that the winger was due to be out for a prolonged period of time, but Hull FC head coach Lee Radford says the positive news is that it is weeks rather than months for the former Melbourne Storm player.
“It’s a tricky one as knee injuries can often go one way or the other, it could have been a matter of weeks, months of even the season, but the news is positive,” Radford told Hull FC‘s official website.
“He had a scan ladt night and the experts think he’ll only be out for a month or so, probably about four to six weeks, so that is really good news for the lad. He’ll have a routine operation to sort it out and straight into rehab with our medical team who’ll manage him back to fitness over the coming weeks.
“We won’t rush him back until he’s ready to play, especially with it being so early in the year, but when he is ready to go I’m sure he’ll be desperate to get back to where he left off. Mahe started the season well, but with the squad we’ve got this year we’ve got some excellent options in terms of cover.”
