It's another meeting with the Lions for Paul Heckingbottom's side.
Barnsley will take on Millwall once again at The Den, a second time this season, after our 3-1 victory there back in September.
After our disappointing exit at the hands of Blackpool in the Emirates FA Cup Third Round last season following a replay, Hecky's men will be hoping to make it further this time around against a familiar foe.
Full details regards the date and tickets will be confirmed in due course.
