Luka Modric is an injury doubt for Tottenham Hotspur ahead of Sunday's clash with local rivals Arsenal.
The Croatian was not included in the squad for the weekend's draw at Stevenage in the fifth round of the FA Cup.
Manager Harry Redknapp has also revealed that Emmanuel Adebayor and Benoit Assou-Ekotto are struggling to be fit for the match at the Emirates Stadium.
"Benoit had a small operation at the start of the week," he told reporters. "Adebayor did his knee on Friday morning, he twisted it.
"We thought he might have opened his ligament up, but it's not too bad and then Luka had an unbelievable temperature. He was really ill."
Spurs go into the match 10 points ahead of the Gunners in the Premier League table.
