News of Bournemouth goalkeeper Aaron Ramsdale’s positive coronavirus test “shook” the Premier League club, according to manager Eddie Howe.
Ramsdale initially tested negative but returned a positive test days later.
The 22-year-old was asymptomatic but is one of eight people to test positive from across the Premier League so far.
“I imagine anxiety is there among the players,” Howe told the Daily Mail. “I can only imagine they are feeling the same way as I am.’
“There was not one positive within our group during the early stages and we were comfortable and felt OK,” added Howe, who was the first Premier League manager to take a pay cut during the coronavirus crisis.
“But as soon as you get that one positive test, that changes the mindset of everybody.
“Suddenly everyone feels vulnerable, everyone is alerted to the fact that this is serious and real.
“Then the unknown comes into play. That shook us. We are now waiting for our next testing times to see if anyone else was in contact with the player.”

So far eight people from Premier League clubs have tested positive after 1,744 tests including Ramsdale, Watford defender Adrian Mariappa and Burnley assistant manager Ian Woan.
The results of the third round of coronavirus tests results are expected to be made public on Wednesday.
Squads started non-contact training last Tuesday for the first time since the Premier League was suspended on 13 March because of the pandemic, with 92 fixtures remaining.
The government has since approved guidance that allows elite sport to return to contact training, and the league discussed that with captains, managers and representatives from the Professional Footballers’ Association and League Managers’ Association on Tuesday.
On Wednesday, clubs will vote on whether to return to contact training. If they vote in favour it could come in this week.
Clubs will discuss further issues on Thursday including the use of neutral stadiums, how to decide the season in the event of curtailment and voting on rebates to broadcasters.
Speaking on Friday, Premier League chief executive Richard Masters said the league was “as confident as we can be” about restarting in June.
