Henry Sembdner was alert and doing better, but not yet talking, his family said Sunday.
On Friday, the 7th grader was slammed to the ground after bumping into another student at middle school, police said.
He suffered multiple facial fractures. He was taken to an Illinois hospital and then airlifted to another to receive treatment for "severe injuries."
The other student was taken into custody.
A candlelight vigil was held Saturday night for Sembdner.
