With University of Mississippi Chancellor Dan Jones on his way out, state Higher Education Commissioner Jim Borsig says the state College Board will launch a national search to replace him.

Jones and the board Thursday said they couldn't reach an agreement to extend his contract, scheduled to end in September. Trustees offered Jones an extension that would have forced him to retire in June 2017 after protests over his nonrenewal. But Jones says he didn't want to be a lame duck leader and should quit if he didn't have the board's confidence.

Trustees say Jones hasn't done enough to improve financial and contracting management at the University of Mississippi Medical Center in Jackson. Jones says management is improving.

The decision provoked widespread protests by many alumni, students, faculty and donors.
