Damar Hamlin collapses on the field with possible cardiac arrest after making a tackle

Damar Hamlin has what appears to be cardiac arrest while playing on MNF. He takes a hit to the chest when making a tackle, gets up, and then falls back to the turf. This hit to the chest could have been the cause of the V-fib. They were performing CPR on the field in an attempt to revive him. I believe this to be similar to what happened to Danish soccer player Christian Eriksen in 2021
