The arraignment for Lacey Plaisted, the wife of BYU basketball center Trent Plaisted, who is being charged with prescription drug DUI was postponed Monday.

Springville prosecutors have charged Plaisted, 21, with a first offense Class B misdemeanor DUI and a Class C misdemeanor stemming from a traffic stop Dec. 13 where a Utah County sheriff's officer observed Plaisted run a stop sign and exhibit irregular "signals in her driving pattern," police said. It seems Plaisted had been taking painkillers for a recent knee injury.

Plaisted, 21, was slated to appear in Springville Justice Court today, but her attorney Greg Stewart arranged for the arraignment to take place Feb. 4, said City Prosecutor Paul DeWitt.
