    \caption{Description of the mandatory Match Sheet Data CDF fields. Any description ending with a $^\star$ is repeated once per player. Only players named to the match day squad are listed. Any description ending with a $^\dagger$ is repeated once per event. Note that \{i\} is used as an index for the items in a list. Figure~\ref{fig:match-data-json} describes the specific format for providing results.}
