Odd/usual injuries during basketball games

[KJUmp]

Partner went to retrieve a ball that went OB at the corner of the end line and sideline and bounced near the end of the bleachers (small gym). He went to administer throw-in, and his arm was bleeding like a stuck pig. When he had grabbed the ball near the bleachers, his arm caught a piece of the metal bleachers. Plius, he now has blood on his shirt. Trainer patched up the arm, he did not have a spare shirt, my spare was too small. We finished game with him wearing a white T shirt.
