Albion will face Leeds United top scorer Raphinha at Elland Road.
The ten-goal Brazilian was one of two players to limp out of the midweek defeat by Chelsea.
But boss Jesse March was upbeat about both Raphinha and Jack Harrison today – especially the former.
Marsch said his exit was precautionary and described him as “fit and ready to go” as Leeds prepare to face the Seagulls.
Harrison took a knock in the first half and limped off but Marsch offered a hopeful, if not definitive, update today.
He said: "Jack Harrison with the contusion looks positive. He should be in training tomorrow and ready to go.”
It remains unclear whether Patrick Bamford will be passed fit after a foot injury as relegation-threatened Leeds prepare for what is being seen as their biggest home game for years.
