MILLWALL will host Portsmouth in the southern section of the first round of the EFL Cup.
Games are scheduled to take place in the week starting August 9, but clubs can mutually agree an alternative date between July and August 4, the week before the start of the EFL league campaigns.
The Lions begin their Championship schedule at QPR on August 7.
Millwall last met Pompey in the second tier in April 2012, when Harry Kane’s goal gave the Lions a 1-0 win at Fratton Park.
