The latest round of EFL coronavirus testing has returned eight positives from a total of 2213 tests on players and staff in the Championship, just three days before games return.
According to Dailymail sport report, the EFL says that the eight positive Covid-19 tests are from six clubs.
Championship side Brentford, who restart their season at fellow London club Fulham on Saturday, confirmed on their official Twitter account that one of their staff had returned a positive test.
In League One, there were two positives from 254 tests across four teams and in League Two, there were zero positives from 174 tests.
Individuals who test positive must now self-isolate in line with EFL guidelines, and will not be able to re-enter a club training facility until they have provided a negative test.
The League Two play-offs begin on Thursday, while League One action begins on July 3.
