Millwall began their pre-season training camp in Scotland on Wednesday afternoon.
The Lions squad - including all five summer signings - travelled up by train from London to Edinburgh and arrived at their training camp shortly before 3pm.
There was time for some lunch before the group headed out for their first training session, which lasted around 90 minutes, ahead of a return to the hotel for dinner and to watch tonight's Euro 2020 Semi-Final between England and Denmark as a group.
