Tottenham’s preparations for their pre-Christmas fixtures have been disrupted by a coronavirus outbreak at the club.
It is understood a number of players and club staff have returned positive Covid-19 tests.
More PCR testing is due to take place over the next 24 hours.
Spurs are due to face Rennes in a crucial Europa Conference League group game in London on Thursday before a Premier League trip to Brighton on Sunday.
Under Uefa regulations, if they have 13 available players, including a goalkeeper, from their 25-man A list, they must fulfil the Rennes fixture, which they need to win to stand a chance of qualifying for the final 32.
The game could be postponed if they do not have sufficient player numbers but all group matches must be completed by 31 December.
