Browns CEO Joe Banner met with the assistant coaches this morning and told them they'd receive permission to interview with other clubs on a case-by-case basis, a source told

The assistants are all still under contract, but most are expected to be gone soon.

The Browns new head coach will have the flexibility to hire his own staff, and won't be required to retain any of the current assistants, including offensive coordinator Norv Turner or defensive coordinator Ray Horton.

The Browns will start interviewing head coaching candidates soon, and high on the list will be Patriots offensive coordinator Josh McDaniels and Penn State head coach Bill O'Brien.

O'Brien has already interviewed with the Texans and is expected to be pursued by other teams, including the Vikings.

Horton is expected to be interviewed for some of the head coaching vacancies. He was recently named a quality candidate by an NFL panel seeking to increase minority hiring.

Banner and Browns owner Jimmy Haslam will address the media Monday at 12:30 p.m.
