Ten individuals from eight Championship clubs tested positive for novel coronavirus in the latest round of tests, the English Football League (EFL) confirmed on Saturday.
In a statement the EFL said 1,058 players and staff from England's 24 second-tier clubs had been tested for the Covid-19 disease on Thursday and Friday.
"Those players or club staff who have tested positive will now self-isolate in line with the guidelines provided by the EFL and only those who have tested negative will be permitted to enter training ground facilities," a statement read.
The EFL did not identify the individuals although Preston North End confirmed that striker Jayden Stockley had tested positive and was asymptomatic.
