The former New Zealand international, who joined the Vikings from Catalans Dragons in the close season, underwent surgery on Wednesday and took to social media to confirm his worst fears.
Just to clear the air on those wondering, since I’ve just had my op a few hours ago, now I’m pretty sure I can say it’s about 10-12 weeks on the sideline. Sorry @WidnesRL fans.. I’ll be back even stronger then before. Let’s keep supporting our team and this great club!! pic.twitter.com/htqJavTmVI— krisnan nevada inu (@krisnan_inu) April 4, 2018
Inu made an impressive start to his Widnes career with six tries in his first six appearances and kicked two goals against the Wolves before sustaining the injury.
It is the second major injury blow for the Vikings, whose winger Patrick Ah Van broke an arm in the opening game against the Dragons in February.
However, there was some positive news for Widnes supporters with the announcement of a new two-year contract extension for Danny Craven.
The 26-year-old has been with the Vikings since the age of 17 and has scored 199 points across 88 appearances at full-back, half-back and centre.
Coach Denis Betts said: "I am pleased that Danny has committed to Widnes Vikings for the next two years.
"Danny has been progressively getting better and better throughout his career.
"Through going on loan and also earning a run of games in the team, he has matured, grown in experience and shown his abilities as a player. "
Craven, who spent the 2016 season on loan at Featherstone Rovers, added: "I've been here for a long time and I believe that this is a great club to be at.
"We have a fantastic set of young players coming through and I am excited by their potential and what we can achieve together."
