It didn't take me long to find it again, but this quote summed it up for me at the time:
How common is this injury? According to Dr. Robert Watkins Jr., orthopedic spine surgeon and co-director of the Marina Spine Center in Marina del Rey, California, it is relatively infrequent among professional athletes.
"Compression fractures are common in the elderly with weak bones but are pretty rare in young athletes," said Watkins, who treats numerous athletes of all levels.
Romo was breaking down. I mean, his back was already at risk in 2014 when he was 34. This was 2 years later. At age 36. After missing almost an entire season with other broken bones.
He gave this team everything and by 2016 there was nothing left. It sucks, but you know it's true.
