ST. LOUIS -- The St. Louis Blues are on the cusp of falling below the Stanley Cup Playoff cutoff line in the Western Conference, and with the NHL trade deadline four days away, general manager Doug Armstrong isn't waiting around for asking prices to escalate.

The Blues on Saturday acquired defenseman Jordan Leopold from the Buffalo Sabres in exchange for a second-round and a conditional fifth-round pick in the 2013 NHL Draft that can become a fourth-round pick if the Blues win one playoff round.

Leopold, 32, has eight points (two goals) and is a minus-6 in 24 games for the Sabres this season. The Blues will be his sixth team in a career that began in 2002-03.

With Douglas Murray traded from the San Jose Sharks to Pittsburgh Penguins for a pair of draft picks earlier in the week, Armstrong said he felt the barometer was set and he was ready to strengthen the left side of his defensive unit as a result.

PITTSBURGH -- Pittsburgh Penguins captain Sidney Crosby needed oral surgery Saturday afternoon after taking a puck to the mouth during his first shift of the Penguins' 15th consecutive victory, according to coach Dan Bylsma.

"He went to the hospital [to] have oral surgery," said Bylsma, who added that Crosby lost some teeth. "We'll continue to evaluate and monitor that."

The NHL's scoring leader left the ice with his mouth covered by a towel after a Brooks Orpik slap shot from the left point perhaps was deflected on its way to striking him. Crosby, who was in the lower inside left circle facing away from the net, immediately dropped to the ice, tossing his stick to the side. A small pool of blood formed on the ice.

Crosby was down for several seconds but skated off under his own power accompanied by team training staff. He went to the Penguins locker room and did not return to the game, won by Pittsburgh against the New York Islanders, 2-0.

NEW YORK – Tampa Bay forward Nate Thompson has been suspended for two games, without pay, for delivering an illegal check to the head of New Jersey Devils forward Matt D'Agostini during NHL Game No. 502 in Tampa on Friday, March 29, the National Hockey League's Department of Player Safety announced today.

Under the terms of the Collective Bargaining Agreement, and based on his average annual salary, Thompson will forfeit $9,729.72. The money goes to the Players' Emergency Assistance Fund.

DETROIT -- There wasn't a game Saturday at Joe Louis Arena, but it sure was a busy day on the ice and in the Detroit Red Wings locker room.

It started with rookie free-agent acquisition Dan DeKeyser, who's from suburban Detroit, signing an entry-level contract prior to his first NHL practice then leading the Red Wings in stretches before getting a stick-tap welcome.

After practice, news started breaking right there in the locker room -- Red Wings coach Mike Babcock told reporters that injured veteran forwards Johan Franzen (lower body) and Mikael Samuelsson (finger fracture) were cleared to play against the Chicago Blackhawks in Sunday's NBC Game of the Week (12:30 p.m. ET) at Joe Louis Arena.

"Samuelsson and Franzen are cleared to go," Babcock said. "So we'll decide [Sunday] morning when we get in here on a lineup and all of that. I don't even know where we are roster-wise and all of those things right there, so we have to get all of that worked out."

The Philadelphia Flyers have acquired defenseman Kent Huskins from the Detroit Red Wings in exchange for a conditional seventh-round selection in the 2014 NHL Draft.

Flyers general manager Paul Holmgren made the announcement Saturday before the team played the Boston Bruins.

Detroit will receive Philadelphia's seventh-round selection in 2014 if Philadelphia signs Huskins to a 2013-14 contract prior to Oct. 1.

Huskins is in his seventh NHL season, his first with the Red Wings. He has appeared in 11 games, going scoreless with an average of 15:20 of ice time.

The 6-foot-4, 210-pound defenseman from Almonte, Ontario has played 310 NHL games, recording 67 points (13 goals) and 173 penalty minutes.

PITTSBURGH -- Roughly 12-1/2 hours after touching down here, Jarome Iginla was making his Pittsburgh Penguins debut.

The veteran forward had his visa issues resolved Friday, caught some good luck connecting flights from Calgary to Chicago to Pittsburgh, and arrived in his new NHL home around 12:30 Saturday morning.

At approximately 1:08 p.m., Iginla was on the ice for the faceoff against the New York Islanders with his streaking, star-studded team.

"When I called Jarome, he said, 'If you can make a spot for me, I want to get on that ice with our team,'" Penguins coach Dan Bylsma said about two hours prior to game time. "So is it ideal that he flew yesterday and got in last night? It's not the perfect situation, but I know he's 100 percent wanting to be on the ice today, be on the ice with the team. And we're happy to put him in there."

DALLAS -- Jaromir Jagr became the 12th player in NHL history to reach 1,000 career assists when the 41-year-old helped set up Dallas Stars teammate Jamie Benn’s power-play goal at 2:10 of the third period against Minnesota on Friday night.

Jagr fed Ray Whitney near the left post. Whitney then slid the puck across the ice to Benn, who one-timed the puck from below the right faceoff dot into the open side of the net.

Jagr’s first assist came on Oct. 19, 1990 -- with the Pittsburgh Penguins, he assisted on a goal by Zarley Zalapski in 4-4 tie with the Buffalo Sabres at the Memorial Auditorium.

After Sheldon Souray's point blast with just 2:08 left in regulation hit the Blackhawks defenseman's stick and redirected past Emery for Anaheim's game-winning goal in the Ducks' 2-1 win on Friday night at United Center, Hjalmarsson heaved his stick at the boards in disgust. He looked like a golfer whose tee shot headed straight into a lake.

It's been that kind of season for the Blackhawks against the Ducks, the team right behind first-place Chicago of the Western Conference standings. Anaheim (23-7-4) not only ended a four-game losing skid, but also swept the three-game season series against Chicago and downed the Blackhawks at the "Madhouse on Madison Street" for the second time.

"I just tried to block it at the end there, and it bounced off my stick … nothing I can do about that," Hjalmarsson said. "I tried to block his shot as much as I could, but you've got to let it go and try to win the game."

The top-seeded team in the NCAA West Regional is gone.

Jesse Root scored 9 seconds into overtime to give fourth-seeded Yale a 3-2 victory against Minnesota in the first regional semifinal Friday in Grand Rapids, Mich.

Kenny Agostino -- one of the players traded by the Pittsburgh Penguins to the Calgary Flames in the Jarome Iginla deal -- intercepted Minnesota defenseman Ben Marshall's pass behind the net and fed Root, who beat Adam Wilcox for his 10th goal of the season. It was the fastest overtime goal in NCAA Tournament history.

Lubomir Visnovsky

Defense - NYI

GOALS: 3 | ASST: 6 | PTS: 9
SOG: 44 | +/-: 2

Visnovsky, 36, has three goals and six assists in 22 games with the Islanders this season, and he's been on ice for 34 of the 59 goals scored by New York in those games. He could have become an unrestricted free agent on July 5.

The Islanders acquired Visnovsky from the Anaheim Ducks on June 22, 2012, in exchange for the Islanders' second-round selection in the 2013 NHL Draft. He played the previous three seasons with the Ducks and led all NHL defensemen with 68 points in 2010-11.
