Mississippi State head coach Mike Leach was transported to the hospital by ambulance from his home Sunday with a "personal health issue," the school announced in a statement on Sunday.
The school announced Monday that Leach "remains in critical condition."
Mississippi State added it will provide more information on Leach's condition via social media once it becomes available.
Mississippi State defensive coordinator Zach Arnett has been placed in charge of the football team until Leach returns. The Bulldogs are preparing to face the Illinois Fighting Illini in the ReliaQuest Bowl on Jan.
