And in further managerial developments in League One, Plymouth boss Ryan Lowe has resigned from his Home Park position as he looks set to replace sacked Preston North End boss Frankie McAvoy.

However, he's being heavily-linked with the vacant position at Ipswich and a return to the game, with William Hill offering odds of 13/10 and BetVictor having Harris as evens for the role,
