Muscle injuries are very common in sport. Over the past decade several classification and grading systems for muscle injuries have been published. This FastFact highlights the MLG-R system that has been developed in collaboration with the FC Barcelona medical department 1 . A good classification system is necessary, which allows to have reliable epidemiological data, which are the base to improve our knowledge about muscle injuries; better knowledge leads to better therapeutic options, prognosis, RTP criteria or lower re-injury rates. The MLG-R proposal is an acronym which refers to the mechanism of injury (M), location of injury (L) , grading of severity (G) , and number of muscle re-injuries (R) .
