Earls, a redshirt freshman from Virginia, was carried off the field on a stretcher Saturday after colliding with Virginia defensive end Jeffrey Fitzgerald.
Earls was rushed to the University of Virginia Medical Center, where he passed a series of radiological tests.
"We took precaution yesterday because our worst fear was that there could be damage to the cervical spine," Georgia Tech team physician Dr. John Xerogeanes said Sunday. "In any situation such as that, we are going to err on the side of caution."
X-rays, CT scans and an MRI all were negative, and Earls was released Sunday morning.
Earls caught two passes for 21 yards and returned one kickoff 21 yards in Tech's 28-23 loss to Virginia.
