Chelsea have admittedly been battling a serious injury crisis this season, with 11 players due to be absent from the game against Crystal Palace on Sunday.
Joao Felix's red card ensured he will serve a three-match ban, with Denis Zakaria also going off injured on Thursday night.
They join Reece James, Raheem Sterling, N'Golo Kante, Wesley Fofana, Ben Chilwell, Armando Broja, Ruben Loftus-Cheek, Christian Pulisic and Edouard Mendy on the sidelines.
Potter admitted the club are suffering, but insisted he has the support of the players.
"I think everybody at the club is suffering," he said.
"You're looking for answers - you're not looking for somebody to blame - but you're looking for a simple answer and it's obviously not that simple.
"The players are supportive, they want to do better than they are and they want to get good results. We know the challenges that we have, but we don't want to use them as an excuse, but they are what they are.
"I thought the players down to 10 men, kept going, the spirit of the team was good, the attitude of the team was good.
"(Going) down to 10 men it's not easy to do it, like I said I don't think Fulham did that much and I was disappointed with the goal, but we kept pushing as well.
"So I don't see any problem with their mentality, I just think that we have to improve."
