an injury you get playing sports such as sprained ankle i hope that answers your question
There are two. The IR, which is the Injured Reserve, and the PUP list, or the Physically Unable to Perfrom list. Also DL for Disabled List.
Because you work your bones and muscles during sport and they can get hurt easily!!!
Fractures account for 5-6% of all sports injuries.
Some one died in football (soccer)
