Manager Tim Sherwood has provided a fitness update on his squad ahead of weekend's meeting with Stoke at Villa Park.
Adama, 19, has been struggling with an ankle problem since being forced off in the second half of August’s 5-3 Capital One Cup third round victory over Notts County after finding himself on the receiving end of a hard challenge.
After several weeks on the sidelines, the £7 million summer signing from Barcelona made his comeback as a 69th-minute substitute in last weekend’s 3-2 defeat at Liverpool but then lasted just an hour into the Under-21 side’s 1-0 loss to West Bromwich Albion earlier this week before having to be replaced.
Sherwood is now set to talk down with the teenager winger to discuss his status ahead of the Potters clash but, unless 100 per cent fit, he looks set to miss out on the game.
“Adama is struggling,” said the Villa boss. “He’s played in an Under-21 game, when he was limping one minute and the next he wasn’t, so I’m going to have a chat with him to find out what’s going on and make a decision from there.
“He picked up that ankle injury against Notts County from a bad tackle but he’s got to get used to that. Unfortunately, it’s taken a little bit longer than we thought and he’s come back and still felt it a bit.
“We can’t take any risk with him. There’s still an awful long way to go in this season and we’re going to make sure he’s 100 per cent.”
Sherwood is confident that Idrissa Gana will be available for the weekend, though, despite some lingering pain following a recent hamstring strain.
The 26-year-old midfielder suffered the injury during Senegal’s 2-0 victory over Namibia last month and missed a run of three games before returning to start against Liverpool after undergoing specialist treatment back in France.
The former Lille man looked somewhat sluggish at times, despite lasting the full 90 minutes, but Sherwood believes he will be fine to face Mark Hughes’ men at Villa Park after receiving further treatment this week.
“He’s fully fit but he’s had a bit of treatment on that hamstring this week,” added the Villa boss. “It’s still niggling away at him but we’re hoping he’ll be fine.”
