Internet sensation Craig Bryden, the Pompey Pirate, dropped into the club’s training ground on Tuesday.
He met with manager Paul Cook and the first team squad as they prepared for their game against Plymouth.
Craig will be the club’s guest mascot for the Argyle encounter to celebrate his inspirational approach to fighting terminal lung cancer.
The former naval steward, who survived the sinking of HMS Sheffield in the Falklands, dressed up in a pirate costume ahead of his first chemotherapy session last month to cheer up others in a similar position.
His photograph went viral after a passenger got chatting to him on the bus to QA Hospital and posted a selfie with him on Facebook.
Cook, who chatted with Craig in his office before the players’ afternoon session, said: “Craig’s story is an inspirational one. We were delighted to welcome him to the training ground and show him around.
“To react in such a positive way to such devastating news is truly incredible and he has the best wishes of everyone at Fratton Park. We hope he has a day to remember on Saturday.”
Craig will be accompanying Nelson on his mascot duties this weekend, in a costume supplied by the Pink Party Shop in Waterlooville and brandishing a special Pompey Pirate banner provided by the Hampshire Flag Co Ltd, before settling down to watch the match.
