Aston Villa v Rotherham (KO 19.45)
Aston Villa host Rotherham tonight with Nathan Baker (ankle), Ciaran Clark (head injury) and Antonio Luna (knock) their only injury concerns.
Villa boss, Paul Lambert, may give new signings Nicklas Helenius and Aleksandar Tonev their first starts after they appeared from the bench in Saturday's loss to Liverpool. Yacouba Sylla and Chris Herd might also play.
Rotherham have not beaten Villa since 1959 and the two sides last met in a competitive fixture in 1972. The teams played each other in the inaugural League Cup final, which was contested over two legs in 1961. Villa won the tie 3-2 on aggregate.
Villa beat Manchester City in the same competition last season, but were knocked out by League Two side, Bradford, in the semi-final. The Villans have won the League Cup five times, with their last success coming in 1996 with a 3-0 win against Leeds.
Nottingham Forest v Millwall (KO 19.45)
Forest striker, Simon Cox, hopes to return from injury. The Irish international picked up an ankle injury in the opening round of the competition. Darius Henderson may also return from a hamstring problem.
Jamie Paterson, Ishmael Miller and Matt Derbyshire, who all came off the bench during Saturday's draw with Watford, may start.
Striker, Steve Morrison, is absent for the visitors after a hernia operation. James Henry and Jermaine Easter are also doubtful but Liam Trotter might appear for the first time this season as he returns from a knee injury.
Forest have a strong history in the competition, having won it four times. Their last success came in 1990 under Brian Clough.
Stoke v Walsall (KO 19.45)
Stoke boss, Mark Hughes, says he will name a strong side tonight. Former Birmingham midfielder, Wilson Palacios, is fit after minor surgery and Brek Shea is also available after missing the Potters' first two games with injury.
Walsall manager, Dean Smith, may bring defender, Andy Taylor, back into the squad as he returns from a pre-season injury.
The sides last met each other in the FA Cup in 2006, with Stoke winning the tie 2-1. Walsall's last victory over their opponents came in a league match in 2002, winning 4-2. Walsall have not won away at Stoke since 1989.
