(CNN)A Dallas area high school has canceled its game next month against an El Paso area high school over safety concerns in the wake of the shooting at an El Paso Walmart.

The Plano Independent School District announced the cancellation of the second annual out-of -district matchup between Plano Senior High School and Eastwood High School in a Thursday news release.

“Our students and coaches were eager for this opportunity to come together with Eastwood High to promote a message of compassion and healing, but what should be a celebratory event would be encumbered by safety concerns for the participants and fans of both teams. Our top priority must be the safety of all,” Superintendent Sara Bosner said.

It was not immediate clear what the concerns were based upon.

    On August 3, a 21-year-old man is suspected to have walked into an El Paso Walmart armed. He told police that his targets were Mexicans. The gunman killed 22 people and wounded 24 more.

    Police say he traveled from a suburb of Dallas to commit the attack.

    The game was set to take place September 6 at Plano Senior High School, near Dallas.

      The cancellation of the game was discussed by superintendents of both districts, according to the news release. While there will not be a game between the two, the booster clubs of each team are working together to promote unity and healing, the release said.

      “Our entire school community felt strongly about showing love and support for the people of El Paso, and I am grateful for the opportunity to continue that outreach,” Plano Senior High School Principal Sarah Watkins said.
