Why are injured players not marked?

Unlike in other sports, handball lacks a central database in which injuries can be reliably entered and a marking of injured players can be automated in an app like START7 based on such a database. Injury statuses in handball are very fast-moving and intransparent. Often, it is only decided a few minutes before the start of a match that players will be absent due to injury.
Therefore, we have to leave it in the managers’ area of responsibility to inform themselves about injuries and to take this into account in their squad planning.
