Former RTÉ Director General Dee Forbes will not attend the Oireachtas Media Committee hearings on the payments controversy at the broadcaster.
A spokesperson confirmed that it's due to health reasons.
It comes as the Media Minister says details of an independent review into the culture and management at RTÉ will be ready by the end of the week.
A two or three person team will also examine the relationship between management and staff in the wake of revelations about hidden payments to Ryan Tubridy.
Cabinet discussed the proposals this morning and expects the work to be completed in a matter of months.
