I'm shocked, was hoping to see him get a run next season, could never fault him for effort which is not what can be said of some of the shower BM picked ahead of him last season.

Gutted. Can't help feeling like he has been forced out.

Are you starting a rumour there?

Just read that he's only 25!

If anyone sees him, say a big thanks from me. I remember moving him and couple of others into a house when he 1st joined. Real breath of fresh air compared to some of the cockiness encountered and would always give 100%. Shame.

Why has he retired, has he sustained an injury? ? ?

Seems bizarre.

Always thought he seemed a decent enought player.

Our farce of a club prefer employing below average Australians and unproven National League players. He probably didn't want to leave London, so had no other option and didn't fancy playing part time.

Mbu was probably on half of what Williamson is on.

Wrong man has gone on both a playing and finances level.

Top bloke and shame he has decided on this at the age of 25.

Like a few on here have said, i to hope the Club keep him on in some sort of role. He would be a great role model for any young players we bring in from the South or even the North of England, his easy going and relaxed manner of the pitch and his more then 100% on it could teach a few of them what to give to the club while here.

We dnt get many Legends at out Club,but you have to fit in some where in that list.

Good luck to you and your new family and hope we still see you at the Club.

Sad day. I guess though with blockbuster back-rowers Williamson and Robinson and other international class players like Ryan Esders there's just no room for another second rower.

And when the inevitable injuries and/or suspensions occur next year, we'll be able to give an “opportunity” to a player from the north who doesn't understand the club and plays with half the commitment Joe shows (and those are the good ones).

And then we'll call it progress.

I do of course wish Joe and his family all the best for the future, but I think I had much to offer the club for many years to come.

Very sad of him to retire at 25, agree with Listy again, he never wanted to leave London, he started his career here, and i guess he wanted to end it.
He had to retire as supporting a young family and playing part time for the Skolars wouldn't be enough income.
Sad for him, was a great guy to talk to, and i know he helped us bring in that french guy, Gigot, as he was fluent in french, and no one else was when Rinaldi left the club.
Was a great guy, he wore his heart on his sleve playing for this club. He loved it.
Sad day tbh.

Joe Mbu would never make a grand final chasing team but as said above he is as good as the disgustingly overpaid Williamson and Robinson. The fact that he has left and those two are still on contract says everything about what a sham Harlequins RL is.

Until David Hughes shows that he gives a damn about losing matches and money, it will get worse and worse until the club loses its super league licence.

Any other owner would have said enough is enough of the trash but not Hughes. I really wonder what his aim actually is.

All the best, Joe - you will be missed. Always gave 100%, and seemed a really nice guy to boot.

Not quite fair to criticise Hughes for this, though - tipping millions of pounds into the club each year shows a degree of commitment even if we disagree with how it is spent!

Real shame to hear this news. Joe was always a real wholehearted player who gave everything. Hope the club give him a send off at the first home game. However, this isn't something they've always done before.
