The White Sox outfielder is expected to miss an extended period of time after suffering a noncontact leg injury while attempting to beat out an infield single over the weekend. The injury has been diagnosed as a Grade III right hip flexor strain and he has already been placed on the injured list.
The injury is a significant one based on the grade alone. Earlier this year, I discussed the classifications strains and sprains receive based on the extent of tissue damage, but let's review once again. A mild or Grade I strain occurs when the muscle is injured, usually at the microfiber level, but the overall integrity of the muscle remains intact. A Grade II strain is considered a more moderate injury and is often called a partial tear. In Grade II injuries, individual muscle fibers fail, but the muscle tissue remains connected to some degree. A Grade III or higher is reserved for complete tears or ruptures, meaning every strand of the muscle is damaged. These injuries are often accompanied by a total loss in function and often require surgical intervention.
Robert suffered a complete tear of his hip flexor. The team will continue to evaluate the injury to determine the precise location of the tear. If the damage occurred in the tendon of the muscle, surgery likely will be the best course of treatment. If the tear is isolated to the belly of the muscle, then extended rest and rehabilitation may be enough for the tissue to
