(NEXSTAR) – If you watch MLB games closely, you might notice not a single-player wears No. 42. There’s one exception to this when every MLB player wears No. 42 on the same day – Jackie Robinson Day.
Jackie Robinson broke baseball’s color barrier on April 15, 1947, as he took the field for the Brooklyn Dodgers. While those playing in the MLB weren’t even alive when Robinson made his debut, the league honors his legacy every year on April 15.
On Jackie Robinson Day, every player and on-field personnel don the number Robinson wore 42, which was retired by the league in 1997. This year, to mark the 75th anniversary of Robinson’s debut, the No. 42 on every team’s jersey will be Dodger blue, regardless of the team’s primary colors.
The MLB has been honoring Jackie Robinson Day every year since 2004, with all players and on-field personnel wearing No. 42 on April 15 every year since 2009.
There will be additional tributes throughout the day on Friday as well. In New York, 42nd Street will temporarily be named Jackie Robinson Way. A sign will be placed at 42nd and Broadway in the afternoon and will then be taken to the National Baseball Hall of Fame in Cooperstown, N.Y.
In Los Angeles, Jackie’s widow, Rachel (who’s turning 100 this year), will be in attendance at Dodgers Stadium as the Dodgers play the Cincinnati Reds. Before the game, Dodgers manager Dave Roberts will bring his team to the Robinson statue outside the main, center-field entrance to pay tribute to Robinson, Nexstar’s KTLA reports.
Robinson was born in Cairo, Ga., in 1919. He attended college at UCLA, where he was named to the All-American football team, but was forced to leave due to financial difficulties, the biography on his website reads. Robinson then enlisted in the Army, but his career was cut short after being court-martialed for objecting to “incidents of racial discrimination.” He ultimately left with an honorable discharge.

In 1945, Robinson played in the Negro Baseball League for the Kansas City Monarchs. Two years later, Robinson joined the Brooklyn Dodgers.
After nine seasons with the Dodgers, Robinson retired following the 1956 season. He went on to work as the vice president for personnel at Chock Full O’ Nuts, a restaurant chain in New York, and became a Civil Rights icon, according to the Library of Congress.
Robinson passed away on October 24, 1972.
