On the 20th anniversary of 9/11, the sports world joined together on Saturday morning to remember all those lost on Sept. 11, 2001.

The 9/11 attacks took the lives of 2,977 people, injured thousands more and forever changed the United States. Now, 20 years after a day that no one will ever forget where they were, the sports community is paying tribute to those lost and looking back on all that took place.

The NFL paid tribute to 9/11 victims during the national anthem before the Dallas Cowboys and Tampa Bay Buccaneers game on Thursday. When the New York Mets and New York Yankees face off at Citi Field on Saturday night, both teams will honor those lost and the Mets will wear special uniforms.
