Seán Cox will attend a charity match to raise funds for his recovery at the Aviva Stadium on Friday.
It will be the first time he will attend an event outside a hospital setting since he was assaulted.
The 53-year-old father of three was attacked almost a year ago outside Anfield, before Liverpool played Roma in the Champions League.
On Friday, a team of Liverpool legends will take on a Republic of Ireland selection to support Seán's medical care.
Friend of the family and head of the organising committee, Stephen Felle, said it will be an emotional evening.
It's going to be Seán Cox's first move outside a medical environment in almost 12 months so it's very special for the family, it's very emotional for Martina.
"I was speaking to her this morning I said does Seán know his going and she said he does and he's excited and she keeps reminding him and he keeps smiling and he can't wait."
