Scunthorpe United and Yeovil Town both triumphed in the additional 30 minutes by a 2-0 scoreline, and Crewe Alexandra edged past Sheffield United 2-1 thanks to a Ryan Lowe brace.
The other game which went to extra-time was a nine-goal thriller between Rotherham United and Morecambe, and the Sky Bet League Two Shrimps won it 5-4 thanks largely thanks to a Jack Dunn hat-trick.

The game between Accrington Stanley and Bradford City, meanwhile, failed to produce any goals after 120 minutes of action, but Stanley took it 11-10 on spot-kicks.

The drama continued on Wednesday night with three games going to extra-time, two of which were settled by spot-kicks.
The story of the night was written by Sky Bet League Two leaders Luton Town, who came from a goal down to beat Aston Villa 3-1. Jake Gray, Cameron McGeehan and a Jores Okore own goal sent the Hatters through after Jordan Ayew’s opener.
