It was announced in mid-December by Celtic manager Brendan Rodgers that Griffiths would be taking some time off to battle personal issues, and a rumour quickly spread suggesting the Scotsman struggled with a gambling addiction.
At the time, Rodgers said: “Leigh will be out of football for a little period of time. He’s had ongoing issues for a number of months.
“He’s reached a point where it’s a struggle for him. We are going to give him all the professional help he needs to get him back in a good place.
“He’s a great guy but football and life is tough for him right now. We want to help him with that and we’ll let you know when he’s back.
“I’m very close with him. We have a strong relationship but he’s had number of issues outside of football.”
“The most important thing for managers and coaches is the welfare of players. It’s no longer a weakness to talk now. He has all of our support – the team, the staff and the supporters.”
A weekend report picturing Griffiths at Newcastle Races caused worry among supporters that he was not battling his alleged gambling addiction well.
But the 28-year-old has posted a message on social media to shed light on his situation.
“Despite what has been written about Me, rumoured or said to you from afar, I just want to settle 1 thing and to make it clear once and for all,” he wrote.
“I am off work due to my mental health state. NOT GAMBLING, DRUGS, or any other issue that has been written about me since December.
“The stories, the tweets, the lies that come out people’s mouths is laughable, but I suppose if they’re talking about me, they are leaving someone else alone.
“If anyone would like to come forward with real evidence that suggests I’m off with the above mentioned either from my employers, or anyone else, let’s see it.
“I’m putting this out there now because family and friends are being asked questions and they’ve been told to say nothing.
“But il not be silenced, especially by newspapers and Idiots who can write tweets and make up stories and it grows arms and legs due to people’s sad and pathetic lives. LG!”
