I looked into this further, and the actual injury was a dislocation (the ball pops out of the socket of the hip joint) and fracture of the femoral head (the ball). Femoral head fractures are very rare injuries, almost always caused by hip dislocation itself.
Most of these can be treated by closed reduction (non-surgically) both of the dislocation and fracture. When closed reduction fails or there are loose fracture segments left floating in the joint, they must be removed, or if they are large enough surgically reattached with wire or screws, etc.
This is not a cue ball. It is a femoral head with large fracture fragment being reduced and secured with a screw.:
This is a very serious injury in that the femoral head circulation is commonly disrupted, especially if there is a large fracture segment as seems to be the case with Pitta. If this is disrupted, there is a high risk of a condition called avascular necrosis, which is basically the counterpart in bone to "gangrene" that occurs in soft tissues.
In summary, this is a very unfortunate injury for this young man........one that is very likely career-ending.........and very likely to ultimately lead to the need for hip joint replacement
