University of Colorado football players reported that jewelry was stolen from their dressing room during the Buffaloes game against host UCLA, officials said Monday.

Following Colorado’s 28-16 loss at the Rose Bowl on Saturday night, multiple players found that personal jewelry left in their locker room had disappeared, Pasadena police spokesperson Lisa Derderian said.

The department is investigating.

In a statement, UCLA said its “athletic department confirmed that a report was filed to the Pasadena Police Department following the UCLA-Colorado football game regarding items that were reportedly missing from the Colorado locker room.”

The university added that it “is in communication with law enforcement, Rose Bowl Stadium officials and the University of Colorado on the matter.”

A spokesperson for the Rose Bowl, the famed off-campus venue where UCLA has played its home football games since 1982, said that stadium personnel are also cooperating with Pasadena police.
