They explained 12-year-old Kassie Graves has serious head injuries.
The accident happened around 3 p.m. Monday on N.C. Highway 751 near the Calibre Park Apartments when Kassie apparently went through a stop sign and into traffic.
Grandfather Robert Graves said the past 72 hours have been a struggle.
"She's pretty much critical since she's been in, and that's all we want to put out there at this point in time," said Graves. "We're just waiting to see what happens."
The family just wants to focus on the middle schooler's recovery.
"Always sadness when something like this happens," said Graves. "A lot of prayers going up and we're just asking everyone to continue to pray for her."
An account has been set up for monetary donations at the SECU Credit Union in the name of Kassie Graves.
