Sheehan has been part of the Bolton side that reached the League One play-offs in each of the last two seasons and won the EFL Trophy in 2023.
The Whites are currently 11th in the table, but the midfielder – who has started 13 of Bolton’s 14 league games – believes that he can be successful with Ian Evatt’s side.

“I believe this season can still be a successful one and hopefully that will only be the start of more good times for myself and the club.
