Kris Versteeg's tenure in Toronto has been a very short one as sources tell TSN that the Toronto Maple Leafs have sent the 24-year old forward to the Philadelphia Flyers in exchange for a pair of draft picks, one of them being a first round pick.

The Toronto Maple Leafs acquired Aaron Voros from the Anaheim Ducks on Tuesday in exchange for a conditional 7th round draft pick.

Voros will report directly to the Leafs' American Hockey League affiliate, the Toronto Marlies.

In 12 games with the Syracuse Crunch of the AHL this season, Voros has no points and 43 minutes in penalties.

ATLANTA -- The Atlanta Thrashers locked up defenceman Dustin Byfuglien to a long-term contract Tuesday.

The US$26-million extension runs through the 2015-'16 season.

"Dustin has emerged into an elite player this season and been invaluable as a leader both on and off the ice," Thrashers general manager Rick Dudley said in a release. "It was a priority to sign him and we're looking forward to witnessing his all-star calibre play for many years to come."

Byfuglien, 25, leads the team with 43 points (17 goals, 26 assists) this season.

He has 152 points (72-80) in 318 career games with the Thrashers and Chicago Blackhawks. Byfuglien has 25 points (14-11) in 39 career playoff games.

He will receive $4.25 million for the next two seasons, $5.75 million in 2013-'14 and 2014-'15, and $6 million in 2015-'16.

The six-foot-five, 265-pound native of Minneapolis, Minn., won a Stanley Cup with the Blackhawks last spring. He was traded to the Thrashers in the off-season.

Leafs general manager Brian Burke said today that Grabovski did not suffer a concussion during the game.

“He would not have been allowed to return to play had he exhibited any symptoms of concussion,” Burke said via e-mail.

Burke added that Grabovski would not need to see a specialist today given a concussion had already been ruled out.

The NHL’s concussion protocol is laid out clearly on its website, with the head of the league and players’ union’s Concussion Working Group Dr. Reuben Echemendia describing the process.

“When a player comes off the ice and is suspected of having a concussion, the team athletic trainer, typically on the bench, will do an initial evaluation,” Enchemendia said. “If that evaluation raises concern with respect to concussion, then that player is taken to the dressing room, where a more extensive evaluation is undertaken by the team physician and the team athletic trainer.

“If at that time the player is determined to have had a concussion, then that triggers the concussion protocol, which means the player must be kept out of play until they are symptom-free, both at rest and on exertion.

“They are also then tested with a neuropsychological -- fairly extensive neuropsychological test battery conducted by the conducting neuropsychologist for each team. Those test data in consultation then go to the team physician, who integrates all of the data and makes the return-to-play decision.”

Because he did not appear to miss a shift in the game, playing close to his regular 19 minutes in ice time, Grabovski was likely only assessed on the bench by a team trainer after being hit by Chara.

In the midst of a breakout season, Grabovski is the Leafs leading goal scorer and is tied for 15th in the NHL with 24 after 56 games. He is expected to play tonight against the Buffalo Sabres.

“I feel bruise in my eyes,” Grabovski told AM640 after the game. “But like I tell it before, it give me more motivation to play harder.”
