As far as a technical, I am still not sure. I did find this on the NCAA site:
The committee is recommending that coaches can request a monitor review of Flagrant 2 fouls by officials at any time during a game. If the replay shows that the coach was wrong, his team is charged a timeout. If the team has no more timeouts, the team is assessed a technical foul for taking too many timeouts. Officials continue to be able to go to the monitor to check these fouls without a request from the coach.
Now, this said Flagrant 2 but I think either can be challenged. Anyway, the language is not clear on this so I am not sure of the exact rule.
