Cam Newton and the Panthers offense are once again in limbo following the departure of offensive coordinator Rob Chudzinski.

Last year marked the first time Newton worked with the same coordinator in back-to-back seasons since high school and the second-year quarterback improved as the season progressed. But with Chudzinski being introduced Friday as the Cleveland Browns new head coach, the direction of the Panthers' offense is unclear.

Coach Ron Rivera declined interview requests Friday, saying in a statement "there's no timetable" to name Chudzinski's replacement.

Rivera fired two offensive assistants Tuesday leaving quarterbacks coach Mike Shula as the only staff member with previous experience as an offensive coordinator. However, Shula struggled in that role with Tampa Bay from 1996-99 and the Panthers could look outside the organization for a replacement.
