Alisdair Gold of london.football now reporting it on twitter. 142,000 followers so should be a good sauce. However, he does say Spurs had cases earlier in the season that were false positive . The affected players have been found positive on lateral flow tests and will take PCR tests tomorrow.
I was going to say something along these lines.
In the realms of sport there does seem to be a surprisingly large number of "false positives" that are resolved with repeated re-tests, freeing up the sportsman to play before he otherwise would.
Six days will allow for a fair number of re-tests.
I guess you keep going until you get the result you want.
