CORONA (CBSLA.com) — A soccer player was accidentally exposed in a picture that was published in a school yearbook in Corona.

“He’s kicking a ball and his pants rode up,” a Santiago High School student, who wished to remain unidentified, said.

CBS2’s Tom Wait reports that the picture was featured in the varsity section of the yearbook. It’s unclear who discovered the issue, but staff scrambled to get the books back to black-out the photo.

Students were told there would be no Grad Night party if the yearbooks weren’t returned.

“The seniors got to go first, starting at lunch. And there’s two lunches. I came at the end of first lunch, grabbed [the yearbook], went to my classroom. And all of a sudden they’re like, ‘Oh, take the yearbooks back, there’s been a misprint,’” the student said.

The student continued, “They’re going around to every single class. My teacher is like, ‘Do you have your yearbook?’ I’m like, ‘Not on me, why?’ The kid next to me did, he goes, opens it to the page, scribbles it out, and checks him off.”

The Corona-Norco Unified School District didn’t say how many yearbooks were distributed or how many were taken back.

The photo, however, has gone viral on Twitter.

Students said the soccer player in question has signed copies of the photo.

Some parents were upset by the situation.

“I hope someone is held accountable for that. Because that’s wrong. Especially if that was my kid,” Devland Lister said.

“You can tell that…things are gone through very, very quickly. And not everything is scrutinized the way most parents would hope,” a parent said.

The district released a statement, which said, “We believe that site administration has responded to the situation swiftly and responsibly, and we hope now to return our attention to what should be the purpose of the yearbook—to celebrate the many great successes of students and staff this school year.”
