The NHL announced Monday that of the more than 250 players to participate in voluntary practices since June 8, there have been 15 confirmed positive tests for the coronavirus, which is roughly a 6% positive rate.

The league has administered more than 1,450 tests to players in that time.

The NHL also says that it is aware of 11 additional players who have tested positive for the coronavirus who have not been participating in Phase 2, which are voluntary workouts at team facilities.

According to the league, all players with positive tests have been self-isolating.

Alexis Lafreniere was supposed to walk on stage Friday night in Montreal as the top pick in the NHL draft.

After the COVID-19 pandemic paused the hockey season and postponed that possibility, Lafreniere was supposed to find out Friday night where he'd be going when the league held its draft lottery. Instead, he'll have to wait.

Chaos reigned at the NHL draft lottery, with the No. 1 pick still up for grabs in a second lottery drawing among the eight teams that lose in the qualifying round of the playoffs -- if play resumes.

The Vancouver Canucks announced Thursday that their city will not be a 12-team "hub" if the NHL restarts its season this summer, despite speculation it had been one of the front-runners.

"From the beginning, our goal was to help the NHL get hockey back on the ice if we could. Although Vancouver won't be a Hub City, we are still excited to see hockey start up again," said Canucks Sports & Entertainment COO Trent Carroll.

The National Hockey League has narrowed its list for the two possible hubs that will host the resumption of the season to six cities, a source confirmed to ESPN's Emily Kaplan.

Las Vegas, Chicago, Los Angeles, Edmonton, Toronto and Vancouver have made the cut so far, with Pittsburgh and Dallas eliminated Tuesday. Columbus was scratched off the list Monday.

The final six cities were first reported by The Athletic.

Veteran forward Chris Thorburn announced his retirement Monday after playing more than 800 NHL games for four different organizations since 2005 and winning the Stanley Cup with the St. Louis Blues.

The National Hockey League has begun winnowing its possible locations to restart the season amid the coronavirus pandemic.

The Blue Jackets were informed Monday that Columbus will not be one of the NHL's hub cities. Columbus was one of 10 finalists, including seven in the U.S.

The NHL announced late Friday that 11 of the 200 players tested since training facilities were allowed to open on June 8 have tested positive for COVID-19.

The league said the players, who weren't named, are self-isolating.

The Tampa Bay Lightning have temporarily shut down their training facility after three players and additional staffers tested positive for the coronavirus.

General manager Julien BriseBois said in a statement that the players have been self-isolating and "are asymptomatic other than a few cases of low-grade fever."

The Buffalo Sabres fired general manager Jason Botterill on Tuesday.

The move comes less than a month after ownership publicly supported Botterill.

"He's our GM. Our plan is to continue with him," team president and co-owner Kim Pegula told the Associated Press in May. "I realize maybe it's not popular with the fans, but we have to do the things that we feel are right. We have a little bit more information than maybe a fan does, some inner workings that we see some positives in."

Kevyn Adams, the team's senior VP of business administration, was named general manager.

NHL commissioner Gary Bettman promises this summer's unconventional tournament "won't be too gimmicky," as the league balances safety concerns with creating a good television product and maintaining the integrity of the Stanley Cup.

"I think everybody can feel good, based on the combination of the play-in round and the way we're going to run the playoffs, that this will be a full competition which will bring out the best in our teams and our players," Bettman told ESPN's Mike Greenberg on Monday. "The Stanley Cup champion will be deserving of that crown and the most storied trophy in all of sports."
