There were also seven positive tests confirmed in League Two.

There were no new positives from the latest round of testing in the Premier League on Thursday and Friday.
Preston’s Stockley, 26, is described by his club “asymptomatic and feeling no ill effects”.
“It came as a complete shock. I got a call from the doctor when I came back from training,” said Stockley.
“I felt brilliant in training, put a good session in and his number came up. We were aware we would get a call if our test was positive and I was thinking ‘no, surely not’, but he told me and it was a surreal moment.
“You feel like you are untouchable and you are going to ride through it.”
The four League Two clubs involved in the latest round of testing were Exeter, Cheltenham, Colchester and Northampton, who occupy the four play-off berths. Teams in League Two have already indicated they wish to end the season but the promotion play-offs are expected to go ahead.

Exeter returned two positives and Cheltenham none.
