Martin Rowlands has returned to QPR after making just one appearance on loan at Millwall.
The midfielder came off the bench in the Lions' 3-0 win at Burnley earlier this month but has otherwise not featured.
Manager Kenny Jackett explained why the 32-year-old had been restricted to just 12 minutes of match action.
"We have had a good run of results and no injuries have opened up the situation for Martin," he told the club's official site.
"All the same, we would like to thank him for all that he has done for us."
