The beards are coming off for World Series Most Valuable Player David Ortiz and outfielder Shane Victorino.
The two Red Sox players will shave Monday as part of a promotion.
Suddenly famous bullpen policeman Steve Horgan and a fan chosen by social media will join them during a shave-off at Gillette headquarters in Boston.
The Red Sox players' beards became a symbol of their solidarity as they went from worst to first and won the team's third World Series title in 10 years.
Horgan became a fixture in Boston after he was photographed with his arms in the air celebrating Ortiz's grand slam in the AL championship series against Detroit.
Boston Red Sox owners John Henry and Tom Werner brought the World Series trophy to center court before the Celtics' home opener against the Milwaukee Bucks on Friday night. They got a huge cheer from the Boston fans still giddy over Wednesday night's victory over the St. Louis Cardinals.
The Celtics showed highlights from the World Series on the scoreboard while the Red Sox anthem "Tessie" blasted over the speakers.
Injured Celtics point guard Rajon Rondo took over Pierce's usual role of speaking to the fans before the opener. Wearing a suit and tie and a fake beard — a tribute to the Red Sox — Rondo welcomed the fans before taking a seat on the bench for the rest of the game.
Boston is preparing for a World Series parade Saturday that's expected to draw hundreds of thousands of Red Sox fans into the city to thank the team for a remarkable season.
The parade is set to begin Saturday morning at 10 a.m.. The players will climb aboard 24 amphibious vehicles at Fenway Park and travel through the city before going into the Charles River.
Security will be tight during the event, with extra police on hand throughout the day and random searches of backpacks along the parade route.
The Massachusetts Bay Transportation Authority plans to run extra trains and subways at a rush-hour level.
The Red Sox beat the St. Louis Cardinals 6-1 at Fenway on Wednesday to take the best-of-seven series in six games.
