Star running back Ty Isaac of left the game—and then the stadium—after banging up his shoulder early against Providence Catholic.
Isaac, who has verbally committed to play at the University of Southern California, got off to a good start, carrying the ball seven times for 67 yards, including a 43-yard touchdown.
But after that, he was tackled hard by three Celtics and landed on his right shoulder. He was shown on ESPNU sitting on the sideline without his shoulder pads.
During the half, ESPN reported that Isaac had left the stadium with his father, Tyrone, for further evaluation at the hospital.
Joliet Catholic coaches wouldn't say what the nature of the injury was when asked by Patch, but ESPN said "he will be OK."
Isaac is the No. 2 player in the state, according to ESPN rankings.
He rushed for a school-record 2,629 yards and scored 51 touchdowns as a junior. He piled up 515 yards and six TDs in the Class 5A state title game last November, a game the Hilltoppers lost to Montini 70-45.
