IHSA to allow girls, boys basketball this winter, defying Pritzker's guidance
In a tweet, CPS said: "We know that this is not the outcome so many of our students, parents and coaches wanted to see. But it will take all of us working together to stop the spread of COVID-19."
This decision comes amid a confusing back-and-forth between the IHSA and Gov. JB Pritzker.
On Tuesday, the state issued new guidelines that put some winter sports "on hold." Then on Wednesday, the IHSA said it would move ahead with basketball anyway. But on Thursday, the governor said basketball would be moved to the spring.
The IHSA told ABC7 it hasn't heard from the state since Tuesday, so it's not comfortable commenting on the governor's latest statements.
