The left-back's long absence has been a source of intrigue to supporters during recent months, but the manager's encouraging comments hint that the 24-year-old is not too far away from playing again.
Malacia was an important part of the squad last season, making 39 appearances across all competitions.
However, he is yet to feature in 2023/24 and, with Luke Shaw and Aaron Wan-Bissaka having recent issues with injury, the former Feyenoord defender would be a welcome option for Ten Hag.
When journalists specifically asked about Malacia in the pre-Luton media briefing at Carrington, the boss gave a little more detail about the player's problems before offering an update on his potential return date.
