I will be more concerned about the health of the player than my bet. Incidents like this happen once in a while that makes us remember that there are some dangers still with the sports. As more of this incidents occur, and although they can be unpredictable, I reason that more efforts will be made by sporting body to make sure that it's occurrence reduces.
I am happy about the health care and emergency aid to players these days, they can still improve, but before some of these incidents would have lead to death because of poor emergency response to players.
