Some fans are questioning if they should watch any football playoff games after Damar Hamlin went into cardiac arrest against the Cincinnati Bengals last month, and was rushed to the hospital. It was a scary moment for everyone in the stadium, but he is recovering fast with doctors.

This incident reminded football fans how dangerous tackle football can be. However, Damar’s injury was not because of football. He just happened to get a cardiac arrest. Some doctors said that he might have suffered the rare disease, commotio cordis. Someone can get commotio cordis when they get struck right over their heart at just the wrong time during their heartbeat.
