The Portland Trail Blazers have closed their practice facility after three positive coronavirus tests came back in a space of four days.
The Blazers were set to have their first full day of training camp today as NBA teams began to welcome players back to their practice facilities for individual workouts last week.
"Over the past four days, we have had three positive COVID-19 test results within our organisation," Neil Olshey, President of Basketball Operations said in a statement released by the team.
"Out of an abundance of caution, having completed contact tracing, we are closing our practice facility today for deep cleaning while we run confirmatory tests."
The Blazers are set to open their pre-season schedule at home on Friday against the Sacramento Kings.
According to the NBA's health and safety protocols, any person who tests positive for coronavirus can return after 10 days in isolation following the date of the first positive test or test negative twice at least 24 hours apart via PCR testing.
Last week, the NBA and NBPA announced that 48 players - 8.8% of players tested - returned positive results in the first week of testing ahead of training camp.
The league is set to begin its 72-game season on Dec. 22.
