Millwall continued their preparations for the 2017/18 Sky Bet Championship season with another gruelling training session in blistering heat on Thursday morning.
The Lions contended with extremely warm temperatures at Calmont Road as they geared up for a first friendly of the summer away to Dartford on Saturday (1pm).
Following that is another pre-season game against Folkestone Invicta next Tuesday night before Neil Harris takes a squad of players to Portugal for a training camp 48 hours later.
