NEW YORK -- The NHL canceled Sunday's preseason games on Thursday. Saturday's games were canceled on Wednesday, a day after the terrorist attacks on the United States.

The cancellations include the Colorado Avalanche's games in Sweden. Attempts are being made to reschedule at least one of those games.

Teams have been given permission by the league to reschedule preseason games amongst themselves.

The Chicago Blackhawks announced on Thursday that their Saturday game at Nashville has been rescheduled for Sept. 23 at 5 p.m. and their Sunday game against Dallas at the United Center has been rescheduled for Monday at 7:30 p.m.

The Oilers and Flames have agreed to reschedule their preseason game for Sept. 19. The game originally was scheduled for Sunday.

The NHL offices in Manhattan were open for a brief time on Thursday. They were closed at 1 p.m. ET and will remain so for the rest of the week. The league will operate out of its office in Toronto.

The New York Rangers called off plans to hold their training camp at Madison Square Garden on Wednesday. The team was scheduled to train at its home arena for the first time in its 76-year history.

Practice was postponed until Thursday, but will be held, without fans in attendance, at the team's training facility in Rye.

Garnet "Ace" Bailey, the Los Angeles Kings director of pro scouting, and Mark Bavis, an amateur scout, were among the 65 people on United Airlines Flight 175 -- the second plane to hit the skyscrapers in New York. The Boeing 767 was scheduled to fly from Boston to Los Angeles.

The Kings, however, opened camp on schedule Wednesday, but postponed their Saturday game against the Anaheim Mighty Ducks before the NHL made its decision to cancel all games.

Once the game is played, the team said all proceeds will be donated to the families of New York City police and firefighters killed in relief efforts.

New Jersey coach Larry Robinson, who coached four seasons with Los Angeles, knew Bailey.

"I lost a friend yesterday," Robinson said. "It just left a horrible empty feeling in the pit of my stomach."

Only the Rangers canceled practice, but other teams struggled to go on.

"It's not an easy thing to try to motivate yourself for practice," Minnesota goalie Manny Fernandez said.

Devils left wing Jay Pandolfo and Bavis were teammates at Boston University.

The Toronto Maple Leafs decided not to go anywhere. Instead of having camp in St. John's, Newfoundland, the Leafs scrapped those plans and remained in Toronto.

On Wednesday, the Maple Leafs held the first scrimmage at their practice rink.

"Even if we could fly, there is no room in St. John's so, unfortunately, we won't be able to go," general manager and coach Pat Quinn said.

Montreal and Toronto are supposed to play each other Sunday night in St. John's.

The Buffalo Sabres hoped to open their camp Wednesday in St. Catharines, Ontario, but changed their minds because of Canadian border concerns.

The Sabres practiced in Buffalo on Wednesday and will try again to shift operations into Canada on Thursday.

"I think for a while it will be very hard for anyone to go about doing anything and feel normal," Sabres defenseman Jay McKee said.

Boston coach Robbie Ftorek also had trouble thinking about the game.

"I never thought I'd say this, but my heart wasn't there," Ftorek said of the Bruins, who opened camp Tuesday. "It's such a tragic thing. You think about all the life that was in those buildings. We went out, and it wasn't a good feeling in my stomach."

Carolina Hurricanes players held a split camp in Raleigh, N.C., and in Fort Myers, Fla., and will do the same Thursday. There are 20 players who are in Florida, and the remaining 33 were supposed to rejoin them Tuesday.

The team's chartered flight was canceled when air travel in the United States was halted following the attacks.

Washington fans came out to Odenton, Md., to catch their first glimpse of scoring champion Jaromir Jagr in a Capitals sweater.

Jagr, traded by Pittsburgh this offseason, appreciated the support even though he didn't think it was appropriate.

Piney Orchard ice rink was filled to near capacity, with many children in attendance because school was called off.

"It's great to see the fans come to the arena, but I think that everybody should concentrate on something else right now, not hockey," Jagr said. "It's pretty tough to do. It's pretty scary. I would say it's a third war."
