Lisburn Distillery goalkeeper Philip Matthews will retire after Saturday's Premiership game against Cliftonville.
The 37-year-old joined the Whites in the 2000-01 season after spells with Bangor, Larne, RUC and Glenavon.
Matthews has made 394 appearances for Distillery and won his only senior medal in the Co-Operative Insurance Cup final success over Portadown earlier this month.
He will remain at New Grosvenor as a goalkeeping coach.
"Philip will come in one night a week and help out with coaching the other keepers," said Distillery boss Tommy Wright.
"We obviously want to thank him for everything that he has done over the years at the club and we understand why he has made the decision.
"But I am delighted that he is still going to stay around the club."
Matthews has surpassed Billy Smyth's goal-keeping record of 355 appearances for the club and he is the only keeper in 130 years of Distillery history to have kept more than 100 clean sheets.
