Rafa van der Vaart is back in the frame for Saturday's Premier League clash against Bolton.
The striker missed last week's 3-1 win at West Brom after picking up a hamstring problem against Villa on November 21.
Harry Redknapp reports that Sandro is also a doubt with a groin injury.
"Rafa trained yesterday (Thursday) and he looked fine," said Harry before training on Friday morning.
"We're not looking too bad. Sandro has a bit of a problem with his groin, we can't seem to get him a run of games at the moment, he keeps getting niggles. He's the only other player struggling short-term."
Harry admitted it was a selection dilemma between Rafa and Jermain Defoe, who scored the key second goal at The Hawthorns.
He added: "Rafa's available, but Jermain's in good form and scored a great goal at West Brom last week.
"I'm very lucky, they are both outstanding players and it's a tough call between those two. To be honest, neither deserves to be left out."
Niko Kranjcar (thigh), Tom Huddlestone (ankle) and Michael Dawson (Achilles) remain out.
