Nuno Espirito Santo insists Boly, who was left out the Black Country derby at Albion, is getting better after suffering with long Covid.
This game, though, comes to soon for the centre-half and the hope is to get him back ready for the trip to Tottenham.
Veteran midfielder Moutinho, meanwhile, having missed the last two matches with an ankle problem, is ready to face the Seagulls.
"Boly is much better. He's recovering and getting better. He's been able to join parts of the sessions," said Nuno.
"We were concerned as we didn't know what was really happening, but now we're more relaxed and aware he needs a couple more days to go back to total fitness."
On Moutinho, Nuno added: "He's better. He's training, totally, with the group. He's going to be available."
