Hill was catching a touchdown pass when his momentum carried him into Caden Thomas on the sidelines Saturday. Caden was among several kids playing on the sidelines as part of a kids' festival at Hughes Stadium, said Caden's father, Mike Thomas.
Neurological exams were normal, so the family opted to take Caden to the hospital on their own after he was initially treated by CSU trainer Terry DeZeeuw and team doctor Sean Grey, Mike Thomas said.
"It was kind of scary," Caden said.
The boy had surgery to stitch up the cut. Tests showed no skull fracture or other trauma, and he was released from the hospital Saturday night, the Fort Collins Coloradoan reported.
"He will have a scar to rival Harry Potter," Caden's father, Mike, told the newspaper.
Caden got a signed CSU football and a call from coach Sonny Lubick on Sunday.
"We had a nice little talk and he had a nice little talk with Caden," Mike Thomas told the newspaper. "I imagine there were 3,000 to 4,000 people there who want to know how he is doing."
