The Jackie Robinson West Little League team has been stripped of its U.S. title for violating geographic boundary rules.

According to the Chicago Tribune, Jackie Robinson West included players on its championship team that were ineligible because they lived outside the team's boundaries. Little League International CEO Stephen D. Keener issued a statement showing sympathy for the players who were not involved.

"What these players accomplished on the field and the memories and lessons they have learned during the Little League World Series tournament is something the kids can be proud of, but it is unfortunate that the actions of adults have led to this outcome," Keener said.

In addition to having its U.S. title win taken away, the team will also vacate all wins from the 2014 Little League World Series. Yahoo News reports that the team's manager, Darold Butler, has been suspended from Little League activity because of the violation.

Jackie Robinson West became the first all-African-American team to capture the U.S. championship after defeating Las Vegas 7-5 last August. The title will be awarded to Las Vegas by default.
