The NHL's bubble plan appears to be working.

About 1,500 daily COVID-19 tests have been conducted in each of the Toronto and Edmonton hubs since teams arrived Sunday, and zero have returned positive so far, according to TSN's Darren Dreger.

The NHL is working with LifeLabs in Toronto and DynaLIFE in Edmonton to administer the tests. Results are processed within 24 hours.

Each team was permitted to bring 52 people into the bubble, and everyone is tested daily.

Every club has played an exhibition game since arriving, and teams have held numerous practices. The qualifying round starts Saturday.
