(REUTERS) - Dutch defender Patrick van Aanholt's late withdrawal from the Sunderland squad to face Tottenham Hotspur last weekend was due to medical advice after cardiology test results, manager David Moyes has revealed.
He was replaced by substitute Jason Denayer shortly before the kick-off in Sunderland's 1-0 defeat by Spurs on Sunday at White Hart Lane.
The 26-year-old has featured in five games in all competitions for Sunderland this season, and will travel to face second-tier Queens Park Rangers in the League Cup on Wednesday.
"He had the statutory checks with the cardiologists," Moyes told reporters on Tuesday. "The Football Association panel advised us really late that he should not play until further tests had taken place.
"I can categorically say that all conspiracy theories are incorrect. It was completely out of our control. We had to make the correct decision for the player and for the football club."
Moyes said striker Jermain Defoe will not feature against QPR after picking up a knock.
"We need to make sure he's fit for the weekend. Some players need game time but some need a rest, so we will take a good team down but we will make a couple of changes," the Scot added.
Sunderland face Crystal Palace in their next league fixture on Saturday.
