Three players test positive in Portugal

Lisbon: Top-flight Portuguese club Vitoria Guimaraes have confirmed that three of its players have tested positive for COVID-19.
The club confirmed that all three were asymptomatic and had been advised by the club to self-isolate, while the rest of the squad would continue individual training after returning last week.
Vitoria's decision contrasts with German second-tier club Dynamo Dresden, who decided to place their entire squad in a two-week quarantine on Saturday following two positive coronavirus tests (for more see entry below).
Second-division side Dynamo Dresden have reported two further COVID-19 cases following a third round of tests.
The whole squad and coaching staff will go into quarantine for 14 days.
The club's sporting director Ralf Minge said: "Fact is that we can't train or compete in the next 14 days."
This means the team will likely not be able to play in their scheduled game against Hannover on May 17.
The football league DFL's Managing Director Christian Seifert told public broadcaster ZDF that the measures were not enough reason to delay the restart of the Bundesliga.
Seifert added, however, that "there is a point when it is no longer feasible. It always depends on how much time you'd have left to finish the season."
