I'll give a better example
You like to jerk off. At some point your wrist hurts. Like really bad. Tendons inflammated or a tear from the rampant fapping.
You rest it. Jerk a bit slower, not as long.
You'll think, damn, stuffs healed.
You start furious masturbation again. Suddenly your wrist hurts very badly again
Here is the deal. Your tendons recover, but in a sport or frequent hobby, they cant recover from the usual stuff as quickly.
In your case, you'll be forced to fap less, after waiting a while to let the tendon recovery catch up
In Marchisio's case, he'll get another 3/4 weeks of strengthening, and he'll probably play less games per week for quite a while.
