The Dallas Mavericks will be without Josh Richardson, Jalen Brunson and Dorian Finney-Smith for at least seven days because of COVID-19 protocols, according to The Athletic's Shams Charania. Prior to departing Denver after beating the Nuggets on Thursday night, the Mavericks learned a player had tested positive. 

It's not yet clear which one of the three tested positive, and which two are simply out because of close contact, but those are the three players involved. The player who tested positive will have to go through the league's health and safety protocols and will have to test negative multiple times before returning to play. Meanwhile, the two who were close contact cases will have to quarantine for seven days.

All three players who are quarantining remained in Denver while the rest of the team, including All-Star guard Luka Doncic, flew back home to Dallas. The only publicly reported player on the Mavs who previously had the virus is Trey Burke, who contracted COVID-19 before signing with the team for the Orlando bubble. In the next seven days, Dallas plays the Magic, Pelicans, Hornets and Bucks

Dallas has had an inconsistent start to the season but stands at 4-4 after a gutsy overtime win against the Nuggets. The Mavs are already without Kristaps Porzingis, who is expected to make his season debut any week now, so missing any additional key players will be a huge blow for a team that has yet to find its groove.
