However, the versatile defender suffered an injury during pre-season that was labeled as ‘minor’, but then was updated to a stress fracture that would keep him out for two months minimum.

Bone continuously degrades under stress and then rebuilds itself (a process known as “remodeling”); this process is how bone becomes stronger.

‘Wolff’s Law’ refers to this bone adaption to the stress exerted upon it.

However, when the balance between stress and rebuilding is off (for instance, by repetitive load), it can weaken the bone and cause a stress fracture as a result of overload.

Bradley most certainly has a stress fracture to a vertebra in the lower back in his situation, which is a stress fracture of the back.
