Had this happen to me in middle school playing some weird game. Kid landed on my knee first right on a kidney. Was sore for the rest of the day and then pissed some blood that night. Parents took me to the doctors and said I had a kidney contusion and to take it easy for a week.
I missed PE for the week and was a sad boy.
When the Wizards play the Pistons you can bet your ass they'll be an echo in the arena lmao
