Aston Villa winger Charles N'Zogbia is set to see a specialist as he seeks to get to the root of a troublesome heel injury.
N'Zogbia has missed Villa's last three matches, with his last appearance coming in the 2-0 home defeat to Swansea on January 2.
With Sunday's FA Cup fourth-round tie at Arsenal looming, manager Alex McLeish said: "Charles will see a specialist [on Wednesday] because he still has pain in his right heel."
He added: "We'll await the results of that before we make a decision on whether he will be involved."
At this stage it is appearing likely Gabriel Agbonlahor, Stephen Ireland and Emile Heskey will all be fit for the game at the Emirates Stadium.
Ireland and Heskey both missed Saturday's 3-2 win at Wolves with hamstring and Achilles injuries, whilst Agbonlahor was taken ill in that game resulting in him being substituted at half-time.
Speaking to the official Villa website, McLeish added: "Gabby is okay and trained [on Tuesday] after a bout of illness which forced him to come off against Wolves.
"Emile has responded well to treatment on his Achilles and he will train later in the week, so he has a chance of making it.
"We're very positive on Stephen and hopefully he will be back training with the group later in the week too."
