Multiple Technical Fouls for a DQ'd Player

[Nevadaref]

The answer is yes, the DQ'd player can still be charged with technical fouls while sitting on the bench. Fortunately, I have never had this be a problem in a game.

I have been in a situation where a player committed his fifth personal foul and before leaving the court was charged with a technical foul for his unacceptable reaction to the personal foul call. I think this is actually fairly common.
