One day after Menlo School’s girls basketball team withdrew from the California Interscholastic Federation state playoffs over coronavirus concerns, the top overall seed in the boys tournament had to do the same Saturday.

Sheldon of Sacramento, the two-time defending Northern California Open Division champion, won’t defend its title after its school district shut down for the next week and canceled all athletic events involving its schools.

The news came hours before Sheldon was to play No. 4 seed Dublin in the Open Division semifinals at Cosumnes River College.

Dublin will now advance to the final Tuesday at No. 3 seed Bishop O’Dowd or No. 2 seed Archbishop Mitty, which are scheduled to play their semifinal Saturday night at Mitty.

With Menlo, a reigning state champion, and Sheldon now done without having lost on the court, at what point is the integrity of the tournament compromised?

“That’s a great question,” CIF spokesperson Rebecca Brutlag said. “That’s something I can’t answer at this time. This is all unfolding as we all go along. I am sure there will be discussions as we move forward. Right now we are moving forward with the tournament as is.”

Dublin coach Tom Costello got the news from CIF director William Chavarin on Saturday afternoon.

“All he told me was the game is canceled, you will advance to play the winner of Mitty and O’Dowd on Tuesday,” Costello said.

Whether the tournament even makes it to Tuesday is another question, given the widespread concern about the virus and caution flags being waved by health leaders.

Asked if he thinks his team will play another game, Costello said, “I have no idea. I honestly don’t know how I feel about it. I am just trying to sort it all out and control what you can control.

“We tell our kids all the time, ‘Control what you can control.’ I am just kind of in shock right now. We’re all fired up, ready to go. The phone call kind of changed everything. We’re still having our shootaround, meeting with the guys right now.”

Chavarin directed media inquiries to Brutlag, but, he added, “We haven’t heard anything from other school districts that are saying they are anticipating closing or closing. As you can imagine, right now it’s more making sure that people are safe.”

The Elk Grove School District, of which Sheldon is part of, notified its families Saturday.

“The public’s health and safety is paramount to Elk Grove Unified School District (EGUSD) and all of our community and educational partners,” the district wrote. “Friday evening, the Sacramento County Public Health Department (SCPH) confirmed that an EGUSD family was put on quarantine because of testing positive for COVID-19.
