Norwich boss Dean Smith says the club are waiting anxiously on coronavirus test results before their Premier League game against Manchester United.
The Canaries' last game was a 3-0 defeat by Tottenham, who have since been hit by a coronavirus outbreak.
Smith does not believe Norwich's Covid-related issues are linked to that game.
However, he admits the club are "worried about a couple of players" before hosting United at Carrow Road on Saturday evening.
"We have got a couple of knocks and have got a couple of Covid-related issues that we are waiting on results for this morning," said Smith, who took over at Norwich last month.
