Blood/sub ?

[deecee]

There can be no blood on the jersey (they would have to fully wash, etc and I dont think that can be done during the game).

They can put on an unused jersey and/or use a jersey off a substitute. Once the jersey has been changed (taken from a sub) that sub cannot re-enter the game without a new jersey which would require a number change and a Technical foul.

However there is no penalty for changing a jersey with blood on it as in using an extra jersey the team packs, or from a sub or even asking the other team if they have a jersey that can be used (ie same color and is not misleading to the teams).
