Reading must wait for Zambia defender Stopilla Sunzu.
The 23-year-old, who has previously had trials at Madejski Stadium, was expected to fly to England in January for a trial. But a call-up to the Zambia squad for the TP Mazembe defender is delaying things.
Reading boss Brian McDermott told the Reading Post: "Stoppy was here when he was a kid.
"It's a possibility that we might have a look at him for a week. He's a good lad."
