The 21-year-old, who spent time on loan with Brentford last season, goes straight into the Shrimpers squad for tomorrow's clash with Oldham Athletic.
Milsom looks set to replace Hal Robson-Kanu who has now returned to Reading after a three month loan spell with Southend.
Robert, a product of the Craven Cottage Academy, has made one appearance for Fulham, in the Carling Cup defeat to Burnley.
He has been handed the squad number 33.
His manager, Roy Hodgson, trimmed the Fulham squad drastically at the start of the season so players like Robert would get a chance to shine.
Hodgson said: "Now, with a squad of only 23 players, of which three are goalkeepers, it will give the younger players, like Robert Milsom and Wayne Brown, a chance to push forward and show what they can do in the first-team squad. It'll give the players on the fringes a greater chance of playing and, although the squad is at the limit in terms of size, at least it's full of the right type of players that we want to be at the club.
