The Welsh winger picked up a knock against Bolton last weekend, whilst Jermain Defoe and Ledley King could also miss the trip to the Britannia
The 22-year-old Wales international, who scored the opener in Spurs’ 3-0 victory over Bolton last weekend, is said to have picked up a knock in the game at the Reebok Stadium.
Jermain Defoe is another who might not feature on Sunday after picking up an injury last week in training, while Ledley King could miss out with an ongoing knee problem.
“We’ve one or two knocks,” Redknapp revealed to reporters.
“Jermain has had a bit of a hamstring [problem] this week, Ledley took a bang on the knee in training last week and Gareth has had a problem this week. We’ll wait and see how they are.”
Midfielder Niko Kranjcar has returned to full training after picking up a thigh injury in October when playing for Croatia.
Redknapp confirmed Michael Dawson is “coming back slowly but surely” from an Achilles injury, but midfielder Tom Huddlestone remains a long-term absentee at White Hart Lane.
