Tom James will return to action in Cardiff Blues' pre-season friendly against Leicester Tigers on Saturday (2.30pm) after being treated for depression.
The Wales international took an extended break from rugby earlier this year to overcome the illness.
He admits it has been a hugely challenging period but is grateful for the widespread support he has received and is now determined to raise the awareness of mental health in sport.
James said: “It is great to be back on the pitch following a difficult few months and I am really looking forward to running out at the Arms Park once again.
“I was absolutely overwhelmed by the support I received whether from my teammates and the staff at Cardiff Blues, my friends and family or the wider rugby family. It has meant a huge amount to me, was a real help and is something I will forever be grateful.
“I am now determined to raise the awareness of mental well-being and help breakdown any remaining stigmas within sport. It is okay to say you are not okay. It is okay to talk.
“I have linked up with Noggin to produce bespoke Cardiff Blues headwear to raise awareness and raise funds for the Mental Health Foundation.”
In two spells at Cardiff Blues, James has so far made 162 appearances, scoring 60 tries, and he is now determined to reach his full potential once again.
He added: “It has been a really tough pre-season, particularly following an extended break but it’s something I’m really enjoying.
“It is great to be around the boys once again, the camaraderie and support they have shown me has been something else.
“It will be great to go up against Leicester, which will be a big test both personally and collectively. I’m just looking forward to playing rugby once again.”
No further comments on Tom’s return to rugby will be made at this time.
