Former Doncaster Rovers goalkeeper Barry Richardson starred in his first league game for 14 years as Wycombe grabbed a shock 1-0 win over Sky Bet League Two promotion chasers Plymouth at Home Park.
The 46-year-old keeper was called into action after 15 minutes following an injury to Alex Lynch - and went on to keep a clean sheet in his first league match since April 2002.
Gozie Ugwu scored the only goal of the game in the third minute for a win which prevented the second-placed hosts going back to the top of the table.
Richardson had two spells at Rovers, making over 50 appearances between August 2000 and December 2001 before returning as player coach in 2005.
He also had a short loan spell at Sheffield Wednesday in 2000, though never played a game.
