The Dutch midfielder joined the Swans on loan from QPR late in the January transfer window but did not feature in Tuesday's 1-1 draw with West Bromwich Albion.
However, Fer could make his Swans bow in Saturday's Liberty Stadium encounter with Crystal Palace if manager Francesco Guidolin opts to make a change in midfield or attack.
"I don't know yet if Fer will play. He has just arrived. He is a new player for me. I know him because I saw him play when he was at Norwich," Guidolin said.
"We needed another midfielder and the club decided to take him. He can play right or left, or No 10.
"I think he is a quality player and I need some days to get to know him better. But it is possible he can play a part of the game.
"We need players with ambition and motivation. I think I need to speak with him because we need players with this characteristics. I will get that out of him."
