Authorities said a preliminary crash report is expected next week for a school bus crash, which injured more than two dozen students.
The bus was carrying more than 60 students when it overturned in Telford in Washington County on Thursday.
Hospital officials said nine students remained in the hospital as of Friday.
The Tennessee Highway Patrol said investigators combed the site on Friday for more evidence. THP said it's still trying to find out what caused the crash.
THP said investigators are examining evidence at the scene, and they are comparing it to statements from the driver and students.
