There are still some potentially brilliant slots of Huddersfield Town’s next fixture list still to be filled.

While 17 of Town’s Championship opponents for 2016-17 are already known, some intriguing promotion and relegation issues need to be settled before the other six are sorted.

Who will drop from the Premier League alongside Aston Villa may become clearer as early as Wednesday night.

Town will definitely face two of Newcastle United, Norwich City and Sunderland, which will be fantastic for gates at the John Smith’s Stadium next season.

Sunderland are favourites to stay up following their win over Chelsea and, should they beat Everton at the Stadium of Light on Wednesday, then they will relegate the other two.

Should former Town player Sam Allardyce’s side gain only a point or lose, then the other two are still in business, although Norwich are desperate for home points against Watford on Wednesday.

Then on Friday, the Campionship play-offs start with Sheffield Wednesday taking on Brighton at Hillsborough (7.45).

Derby then host Hull in the second semi-final first leg on Saturday lunchtime (12.30).

Three of those clubs will be staying down, so Town fans may be rooting for Brighton so that Wednesday, Derby and Hull are added to the strong Midlands contigent already confirmed in the division – Villa, Birmingham, Burton Albion, Forest and Wolves.

Town could be handed another derby, too, in the League One play-offs, as Barnsley and Bradford City are doing battle with Millwall and former Town player Jon Whitney’s Walsall.

Barnsley play Walsall in the first semi-final first leg on Saturday (5.30), with Bradford entertaining Millwall on Sunday (12.15).
