Fulham duo Lasse Vigen Christensen and Emmerson Hyndman are unlikely to return from injury until at least the last game of the season.
Christensen, 20, was in good form before suffering a hamstring injury and has not played since 28 February.
Hyndman suffered a broken collarbone playing for USA Under-20s in January and has not featured for the Whites since December.
Manager Kit Symons said: “Hyndman is likely to be fit sooner than Christensen but it won’t be in the immediate future.
“Neither are back training yet and they definitely won’t be available for the weekend against Blackpool, and probably not for the Middlesbrough game either.
“If anything it will be for the last game of the season – there’s a chance but we’ll have to wait and see.”
