Deadline Day: Here's the biggest deals that could go through in the EFL - including Rotherham, Portsmouth, Sunderland & more

Deadline Day has arrived for sides in League One and League Two, and a number of big deals are set to go through as club's look to bolster their squads, with the season now six games deep.

Clubs have until 5pm this evening to conclude their business, and there should be a number of comings and goings across the two divisions. Here's some of the biggest deals that could go through before the deadline...

The Millers are likely to have a busy day, and a new defender could be on the cards. There's a fair bit of talk suggesting they could bring back their former loanee permanently.

A number of Posh players have been linked with a move to Wanderers, including the former Lincoln City man.

The 26-year-old could well leave the Black Cats before 17:00, with his manager Jack Ross previously admitting the player's future could lie away from the Stadium of Light.
