There is no such thing "minor" injury. If you have had an articulation injury in your life, you know what I mean.
Of course there are: once I had the same traumatic injury (or better, I injured in the same way at the same time) both wrist: the left was practically ok in few hours and I would have played without problems the next day (despite not being perfectly ok), the right needed a month and a half to stop annoying me, and I absolutely wouldn't have been able to play for at least the first month.
Not to speak about my knees, back etc etc... Ok, I play at not agonistic level now so I don't have a medical staff to evaluate every time, but if you think that players play only with zero pain you live in another world I'm afraid... Have you notice how many put the colored stripes on or play with knee/ankles supporters? (Some are used to prevent more injuries on the same articulation, but not all)
