ejected coach

[Dibbs]

In our area Jv games are played first and then followed by the Varsity game. During the JV game the varsity coach will sit on the bench during the JV game and because they are bench personal they get Technical fouls. My question is what if a Varsity coach gets ejected in a JV game, can he still coach his varsity game that follows the JV game?
The same as far as the JV coach, if he gets ejected from his game can he now sit on the Varsity bench in the same night? Has anyone seen this happen and if you did what was done. Thanks
