Millwall midfielder Ben Thompson will spend the remainder of the 2018/19 season on loan at Sky Bet League One side Portsmouth.
Thompson has made 93 appearances, scoring four goals, for The Lions since making his debut in a 2-0 League Cup defeat to Southampton in August 2014 but has found first team options limited in the last 12 months.
As a result, the combative midfielder will link up with former Lions boss Kenny Jackett at Fratton Park, with Thompson hoping to be in the squad for Pompey's League clash with Oxford United on Saturday afternoon.
"It's a real good move for him," said Millwall boss Neil Harris. "It's a tough one with someone like Ben because he's so important to our plans.
"First and foremost, his long-term future lies with our football club. He's a super young player and a fantastic character. In my opinion, he's going to be a good Millwall captain in the future.
"He's gone on a short-term gain for him to get that experience of playing again, to get the minutes in his legs and to certainly help Kenny and Portsmouth keep moving forward.
"There's also one eye on us with development. Last year he was in every squad without always being in the team or on the bench. You have to balance off the fact that it's important to have a squad that is capable of having strength in depth, but also the development of the players.
"Ben's gone with the goodwill to go and play some minutes, but what's important with that is we try not to leave ourselves short."
