The NBA's replacement referees caused confusion in the first quarter of Detroit's preseason win over Milwaukee on Wednesday night.

Bucks forward Ersan Ilyasova was fouled while shooting a jumper and awarded two foul shots. More than 90 seconds later, during the next timeout, the officials decided that he was attempting a three-pointer and gave him another free throw.

Ilyasova made the shot, but Pistons forward Tayshaun Prince pointed out that the error is only correctable within 24 seconds and the point was taken away from the Bucks.

"I told him that they couldn't change it after five minutes or whatever it was, and he said 'yeah, you're right,' " Prince told the Associated Press. "Then I had to remind him to tell the scorer's table to take it back off the board."

The referees called 68 fouls in the game -- 26 more than the average regular-season game last year -- and ejected Carlos Delfino and Austin Daye for fighting in the final minute.

Fellow Detroit rookie Jonas Jerebko was ejected in Monday's win over Miami after a scuffle with Jamaal Magloire.

"I have no idea what I got thrown out for -- I was getting ready to shoot the technical free throws when they told me was I was gone," Daye said. "I know I didn't throw a punch -- it would have been stupid to do that after Jonas got thrown out of the last game."
