Harry Redknapp reports that the flying winger has trained this week and is back in the squad for the 4pm kick-off.
Aaron has been out since suffering a hamstring injury against Stevenage on March 7.
Harry said there were no additional problems after Tuesday night's FA Cup quarter-final win against Bolton.
"We're pretty much okay after Tuesday night," he said. "We haven't too many more problems, most came through that game okay, so we're fine."
