Kansas guard Brandon Rush tore his ACL in his right knee, meaning he may not play for the Jayhawks until December, a high-ranking Kansas source told ESPN.com Monday night.

The school expects to see a final review of Rush's MRI Tuesday. The test results were sent to a Denver specialist over the weekend. An announcement is due Tuesday or early Wednesday from the school.

Rush injured his ACL Thursday during a pickup game and then withdrew from the NBA draft Friday afternoon.
