He's suffering from Uveitis and therefore can't perform currently.
I won't jump the gun and state this as the definite truth yet though :D

Unless it comes direct from us don't listen. People saying according to someone close to the band is SHIT.

All I can say is he is OK. There are personal reasons. I'm sure some can look up the meaning of "personal" reasons.

Wow, Matt is doing killer business for the band Bon Jovi again with these Twitter messages.

Yeah, Matt's Tweets are always so defensive and weirdly passive-aggressive...though I am glad to hear that Richie is 'ok'

Phil x was recently on tour in UK think it's.still going so he wobt.be in

Comes across as a bit of a ****wit alright.

Someone should respond to him and say " We'll you are close with the band, are you saying that everything you say doesn't mean SHIT either?"

In Matt’s defense, people are probably being stupid and annoying. Just based of the comments here, I could imagine what he is getting. Dry County is less than 1% of the Bon Jovi population. Poor Matt

To Matt's credit, though, he did go after that Tweet by 'NaughtybutNiceRob' that claimed 'Bon Jovi Dumps Sambora' by saying, "I think you need a better source."

I'm still not sensing that this is alcohol/drug/rehab - I can't help but think that this was always an album & tour that Jon wanted to do more than any of the others, and Richie has said enough is enough.

We've seen enough articles recently where Dave/Tico/Richie admitted that the album wasn't something they were ready to do so soon after the last tour.

You can argue black is blue all you want. Addiction is officially recognised as both a disease and a genetic predisposition - whether you think it is or you don't, is completely immaterial - I am not commandeering anything other than scientific fact. No need to 'think again', maybe you just need to catch up on some reading.

The fact that you've been personally affected by addiction is something you've decided to bring up, which is obviously meant to both shame me and make me/others think I don't know what I am talking about. It doesn't. Your comment was ignorant, plain and simple. Whether your personal circumstance is/has ever been affected by it doesn't distract from that in the slightest.

Also, I would like to know where on earth I've been rude to you or anyone else? It was pointed out that in 'the real world' Richie would be fired from his job... I argued the case that for the defence. I argued that addiction is seen as a disease and an employer would have a hard time not handing over a large payout in 'the real world' for sacking someone who became addicted to medication that was prescribed to enable them to work. Failing to see how I've been ignorant and rude.

Make some sense, or get back on topic. That was borderline rude, I'll give you that.
