Charlton have agreed a loan deal with Crystal Palace for Sullay Kaikai, Sky Sports News understands.
The 22-year-old winger has been unable to break into the Eagles first team and has made only four appearances this term.
Sky Sports News reported earlier in the January window that Championship side Brentford had made an enquiry about Kaikai.
The winger moved to Griffin Park on loan for the 2016-17 season and scored three goals in 18 appearances, but was recalled in January after Sam Allardyce took over as manager.
Charlton have already signed Stephy Mavididi on loan from Arsenal and Michal Zyro on loan from Wolves this month.
Manager Karl Robinson has been keen to improve the Addicks squad as they push for a play-off place in League One.
