The Premier League has been suspended since mid-March amid the coronavirus pandemic.
Premier League chiefs are eager for the season to be completed though they insist the league will only resume when it is safe to do so.
A doctor has advised players to wear face masks during matches and training.
“Masks tend not to protect you but protect others,” Dr Rowland Kao from the University of Edinburgh said, according to Daily Star.
“They prevent aerosol spray but leaves open (the risk of) fomite transmission – putting your hand to your mouth or your face and then wiping it somewhere else, like a doorknob.
“It’s unclear how much protection those masks would be, but it would seem sensible to put as many precautions as you could in place.
“If you have got 300-500 people coming together (for a match behind closed doors), there’s an opportunity for multiple infections to occur.
“Individuals involved should be tested relatively soon before any such activities occur and should be tested frequently throughout.
“There will be some question as to whether such tests are available. If we’re talking about a substantial number of teams and a substantial number of tests, it’s not clear to me at this time whether that would be viewed as an appropriate use of such testing, if we’re trying to prioritise other areas. If you couldn’t do the testing, it’s unlikely any activity could restart.”
