Saturday marks the 20th anniversary of the 9/11 attacks. Nearly 3,000 people were killed after hijackers flew two planes into the World Trade Center in New York.
In remembrance of the anniversary, athletes, professional sports leagues and teams sent out tribute messages to reflect on the occasion.
Professional teams playing Saturday will likely hold ceremonies to pay tribute to the anniversary of 9/11. The New York Mets — who played the first sports game in New York following the attacks — will hold a remembrance ceremony prior to Saturday's game against the New York Yankees.
