FORMER QPR striker Kevin Gallen, the brother of Millwall assistant boss Joe, has been helping the club's coaching staff in recent weeks, NewsAtDen has learned.
The ex-England U21 international ran drills during the Lions' pre-match warm-up ahead of their FA Cup semi-final defeat to Wigan at Wembley last weekend.
But manager Kenny Jackett says the 37-year-old is unlikely to join his staff on a permanent basis as Gallen's work has been as much for his own benefit as it has been Millwall's.
Jackett said: "We have had more players in the first-team squad over the past two months, so we've needed another coach. It's that simple. Kevin's not on the payroll but is looking for employment.
"From his point of view, coming in for part of the week and helping us out when we are particularly busy is hopefully a stepping stone and good experience for him.
"He is taking his badges now – his UEFA B license, which is the start of the coaching pyramid. Being here has helped him gain confidence as a coach after his playing career.
"I very much doubt that's going to develop beyond the end of the season into a full-time position, but we hope we can help him along the way and he has helped us over the past few weeks."
