Fulham boss Kit Symons fears Marcus Bettinelli could face a long spell on the sidelines after the goalkeeper was stretchered off during the 2-1 defeat at Hull.
Bettinelli collided with team-mate Matt Smith just before half-time as they chased a ball played into the penalty area.
Both men suffered knee injuries and are due to see a specialist on Thursday.
“Marcus’ one is looking quite nasty. Matt hopefully is not quite as bad,” Symons said.
“We obviously won’t know more about that until tomorrow when they see the specialist.”
Tom Cairney’s fine equaliser, cancelling out Ahmed Elmohamady’s first-half opener, looked to have earned Fulham a point until Sone Aluko struck five minutes from time.
And, after dropping a point in injury time against Brighton on Saturday, Symons was frustrated at having lost a game late on again.
He said: “We’re only three league games in and I’m sick of saying the same things already.
“We’ve battled well in games, created chances and been in the ascendancy and come in with little to show for it.
“At Cardiff we got a point, (but) it should have been three, and we should have, at a minimum, got a draw tonight.
“It’s getting really frustrating and really annoying. Something needs to change, sharpish.”
