The University of Oregon issued an alert to evacuate Hayward Field due to a bomb threat Tuesday, June 9.

The emergency alert, sent at around 1:39 p.m., urges UO community members to evacuate the track and field stadium at 1530 Agate St. In a 2:06 p.m. update, UO said university police were expected “to take several hours” to investigate.

The 2026 NCAA outdoor track and field championships are scheduled to begin at Hayward Field on Wednesday.

The NCAA at first announced it would delay a pre-meet press conference planned for Tuesday, and then at 2:22 p.m. said the press conference would be canceled.

At 2:45 p.m., agencies “from across the region” out of an “abundance of caution” were continuing to investigate along with university police, UO said in a third emergency alert.

Last month, the university’s student recreation center was cleared of people after a shooting threat was phoned in. UO police identified no danger after investigating.

This is a developing story and will be updated.
