2-22 12:30 AM, EST - Billy Glidden's medical condition has moved in a positive direction.

Doctors have chosen against doing surgery on Glidden's broken ribs, electing instead to allow them to heal on their own. He suffered five broken ribs and bruised lungs when his 2010 Mustang Pro Modified entry experienced severe tire shake and made an abrupt right turn and impacted the right side retaining wall.

The damaged race car then shot across the track where it impacted the left lane retaining wall before coming to a stop in the right lane. Glidden was knocked unconscious momentarily.

Glidden has significant swelling in his back, but doctors believe this is normal for the trauma his body received. All cat scans came back negative for any potential head injuries.

Glidden will remain in the hospital for two more days, as doctors monitor for blood clots. He remains in stable condition, with positive spirits and according to Shannon, was trying to watch the Indiana University basketball game.

"We cannot say thank you enough to the friends and family members who have offered prayers and support during this tough time," Shannon said.
