Tottenham Hotspur defender Toby Alderweireld has withdrawn from the Belgium squad due to a stomach illness.
The 27-year-old was in line to feature in Tuesday's international friendly against Portugal in Leiria, but the Belgian FA has confirmed the defender's absence.
Alderweireld and his national teammates flew to Portugal last week after the fixture, which was originally due to be played in Brussels, was rearranged following last Tuesday's terror attacks.
The defender has five days to recover before Tottenham take on Liverpool at Anfield in the Premier League.
