The Latics will throw open their doors for just £1 a ticket when they host Kidderminster Harriers on February 24.
When home or away fans are completing the bargain purchase on the club’s website, supporters are encouraged to make a donation to Frank’s fundraising campaign for Alzheimer’s Research UK.
The incredible 73-year-old is over six weeks into trek across the Atlantic Ocean and the Latics supremo has nearly raised £200,000. He says he’s doing it because one in two of us will be directly affected by dementia - and he says he wants to help stop the disease from robbing us of everything that matters.
The club hope to better this season’s leading crowd at the 13,000 capacity venue, with 9,667 watching runaway leaders Chesterfield beat Barnet back in November.
An Oldham spokesperson said: "Frank has been away since the start of December and is now in the final stages of his solo row across the Atlantic Ocean as he raises funds for Alzheimer’s Research UK.
"Having faced some hugely difficult conditions during his journey and capsized three times, he has shown tremendous strength and courage to reach this stage.
"Frank is already the oldest person to ever row across the ocean on their own and he is on course to beat that record.The club is very proud of Frank and wants to fill Boundary Park to give him a hero’s return for his first home game back.
"Although admission is just £1, there is the option to make a further donation to Frank’s fundraising campaign when completing your purchase and we’re encouraging all supporters to give as much as they can.
“Let’s get down to Boundary Park, create a special atmosphere and give Frank the welcome back he deserves!"
