A chip fracture, also known as an avulsion fracture, is when fragments of bone chip off the main bone because the ligament or tendon dethatched and pulled them off during the injury. Yes, it hurts. Treatment time depends on the size of the chip and other factors, they will know more after an CT scan on Tuesday, reports the Denver Post.
However, this is going to be in the ballpark of three weeks or a month, which is pretty common with this kind of injury.
This is incredibly bad news, and could lead to a continuation of the current 5 out of six skid. Sucks.
