Kelly and Harte will share management duties over Offaly's senior footballers next year.
It's expected Declan Kelly's hand will be strengthened by the appointment of Mickey Harte as joint manager of the Offaly footballers.
Kelly endured a difficult first season as the county's sole manager.
Offaly played poorly through large parts of their league campaign, and managed worse in their Tailteann Cup exit.
Sports Editor of the Tullamore Tribune, Kevin Corrigan says despite some difficult moments, the former U20 All Ireland winning manager deserves more time to win at senior level:
