Nottingham Forest are in Carabao Cup quarter-final action on Wednesday night when they take on Wolverhampton Wanderers at the City Ground.
Forest are looking to book a place in the last four of the competition, with Manchester United and Newcastle United having already progressed with victories over Charlton Athletic and Leicester City respectively. Southampton and Manchester City meet in Wednesday's other quarter-final.
Steve Cooper's Reds will be determined to bounce back from their shock 4-1 defeat at Blackpool in the third round of the FA Cup at the weekend. Wolves, meanwhile, come into the game on the back of a 2-2 draw with Liverpool at Anfield.

Here's a couple of key Carabao Cup competition rules that could come into play for Forest, Wolves and the other teams involved at this stage...
What happens if the score is level after 90 minutes?
If the sides cannot be separated after 90 minutes, the quarter-final ties will go straight to a penalty shoot-out. There will be no extra-time.
However, there will be extra-time - 30 minutes (two halves of 15 minutes) - if required in the semi-finals and final.
Rule 12.4 of the competition guidelines states: “In the event of the scores being level at the end of ninety minutes’ play in rounds one, two, three, four and five no extra time shall be played, and the winners shall be determined by the taking of kicks from the penalty mark in accordance with procedures as approved by IFAB.”
Will VAR be in use?
No, VAR will not be in action for tonight's tie. Competition rules state that VAR will only be used in the semi-finals and final.
So if Forest manage to beat Wolves, they will see VAR in use in the next round.
How many substitutions can my team make?
Teams can name nine substitutes in their matchday squad and are allowed to use five of those during the game. These can be made in three goes, not including half-time changes.
Rule 8.1 of the competition guidelines states: “In all Competition Matches, each Club is permitted to name up to nine substitutes on the Team Sheet, of whom not more than five may take part in the Competition Match. Each Club is only permitted a maximum of three opportunities to make substitutions during the Competition Match. Clubs may make substitutions at half time and any substitutions made will not count towards the maximum of three opportunities. A Club may make more than one substitution at each of its three opportunities.”
In addition, teams are also allowed to make "concussion substitutions" if needed. This is the first season the rule has been introduced for the Carabao Cup.
Rule 8.3 of the competition guidelines states: “Each Club shall also be permitted to utilise up to two ‘concussion substitutes’ and/or two ‘additional substitutes’ (as appropriate) from those substitutes listed on the Team Sheet, strictly in accordance with the provisions of the International Football Association Board’s ‘Additional permanent concussion substitutes – Protocol B (‘IFAB Protocol’)’ and any associated guidance issued by the League. Use of either a ‘concussion substitute’ or an ‘additional substitute’ in accordance with this Rule 8.3 shall not count towards the five substitutions permitted to take part in the Competition Match.”
