One NBA source said on Wednesday that the Bucks have reduced their coaching search to two candidates.

The primary object of the Bucks' search is considered to be former Minnesota Timberwolves coach Flip Saunders. But numerous reports say he is in line for the Detroit Pistons coaching job if Larry Brown departs.

Brown was scheduled to check into the Mayo Clinic on Wednesday for a three-day checkup, and it was unclear if the 64-year-old coach would be given a clear medical update by Friday.

The Bucks are believed to be focusing anew on Terry Stotts, the former Atlanta Hawks coach and a lead assistant to George Karl for four seasons in Milwaukee. Stotts served as an assistant on Mike Montgomery's Golden State Warriors staff last season.
