Rodger has been promoted from his position as assistant boss at Blundell Park following the departure of Russell Slade last week.

The former Grimsby defender, 39, has signed a two-year deal with a further two-year option.

"In one of the many interviews for the job, Graham impressed and earned the board's full backing," said a club statement on the Grimsby website.

It added: "He has gained considerable managerial experience under Paul Groves, Nicky Law and Russell Slade, during this time he also stepped up to the role of caretaker manager twice.

"We seriously considered Graham for the manager's position before the appointment of Russell Slade, but felt he needed more time to develop his contacts and knowledge of players at this level.

"We have made it clear to our new manager, there will be financial support to mount a serious challenge for the next campaign."

The League Two club will now look to appoint a new assistant to work alongside Rodger.
