Brighton winger Leandro Trossard has been sidelined with a groin injury.
The 24-year-old picked up an injury in training while he was away on international duty with Belgium.
Brighton manager Graham Potter said: "It's early stages with Leandro but he's felt something in his groin.
"We don't think it is as bad as initially thought.
"He is obviously not going to be available for the weekend and the other side of the next international break is probably what we are aiming for now.
"At this early stage, it's hard to put too much more of a timescale on it."
