Charlton Athletic midfielder Oliver Muldoon has signed a new contract with the Championship club and joined Gillingham on loan.
The 20-year-old, who is yet to make his senior debut for the Addicks, will remain at The Valley until the summer of 2017.
Muldoon, who came through Charlton's youth set-up, will be with the Gills until the end of the season.
The Kent club are 14th in League One, four points off the play-offs.
"Oliver will give us another option in the centre of midfield and he has a good range of passing," said Gills boss Justin Edinburgh.
