Newcastle's Premier League game against West Bromwich Albion is expected to go ahead on Saturday as the United squad recovers from a coronavirus outbreak.
But there are enough players who have tested negative to play the game against Albion at St James' Park.
The Magpies' training ground was closed for a week, but the players returned to full group training on Wednesday.
Players were tested on Monday to assess how many would be available to play against West Brom and therefore whether the match could go ahead.
"Those who had tested positive will follow relevant protocols before returning," Newcastle said on Tuesday.
