The £18million winger, who joined from Middlesbrough shortly before the transfer deadline, has been sidelined for a number of weeks with a dislocated shoulder.
But Nuno Espirito Santo revealed during today's pre-match press conference that after a week of training the 22-year-old is available.
"He's available for tomorrow," Nuno said.
"Adama joined us late, he came with an injury in his shoulder
"He was two weeks out, he started training and is adapting and getting better."
However fellow new boy Leander Dendoncker, a £12m signing from Anderlecht on deadline day, won't be in the squad for the trip to the King Power Stadium.
"It's a different situation," Nuno added. "He came really late, after a period of holiday and the World Cup, he's only one week of training
"He has to be fit...he's not on the list for tomorrow.
"Ivan (Cavaleiro) is not available, he'll be out for a couple of weeks or so (but) from the last game everybody is okay."
"We have to go step by step, we have to put him out of pain then starting slowly progressing on his fitness.
"I hope (he's available) as soon as possible but we have to give him time, he's starting a new treatment now and hopefully we'll get him faster."
Of the prospect of earning their first Premier League win at Leicester tomorrow, Nuno said: "It would mean a lot, it means three points.
"We're going to fight to achieve three points knowing we're going to face tough opposition, Leicester is a very good team.
"We want to compete, (it's not) 'would, could, what, ifs maybe'...reality is what we're focused on."
