It was learned Wednesday that Zeigler had agreed to terms with officials at Central Michigan.
Other sources are indicating that the deal is not quite finalized.
Zeigler came to UCLA with Head Coach Ben Howland three years ago. He's originally from Michigan, which was part of the appeal for the hire.
Most sources close to the UCLA basketball program believe Scott Garson, UCLA's video coordinator, to be the leading candidate to fill the vacant assistant coaching job.
