According to multiple reports, Calgary Flames forward Jarome Iginla is available on the trade market.

"What we believe is going on is that the process had begun to trade him, and the list of teams is very small and it’s Stanley Cup contenders," said the CBC's Elliotte Friedman on the Hot Stove segment of Hockey Night in Canada on Saturday.

Meanwhile, both TSN's Darren Dreger, who is a hockey insider on the NHL Network as well, and Renaud Lavoie of RDS are reporting that four Stanley Cup contenders are on a list of teams Iginla has told the Flames he would waive the no-movement clause in his contract to join. According to both reporters, the Boston Bruins, the Pittsburgh Penguins, the Chicago Blackhawks and the Los Angeles Kings, the defending Stanley Cup champion, comprise the list.

Boston Bruins general manager Peter Chiarelli is walking a very fine line approaching the April 3 NHL trade deadline.

While he has a few spots in mind he'd like to improve his team, he has no interest in altering the core of a group that won the Stanley Cup in 2011.

"You always want to try and improve," Chiarelli told CSNNE.com. "I want to try and keep the roster as intact as possible. I'll never say 'never,' but that's been my objective. I think I've shown over the years I'm trying to keep the core together and I'm going to continue and try to do that."

The injury to Chris Kelly has Chiarelli most focused ont rying to add something to a third line that has struggled to perform consistently.

"We've been trying to fill that hole on the third line and we haven't been able to," Chiarelli said. "That's an area we'd like to improve."

CSNNE.com lists potential targets as the Dallas Stars' Jaromir Jagr and Brenden Morrow and Ryane Clowe of the San Jose Sharks. The Calgary Flames' Jarome Iginla and Jay Bouwmeester also are possibilities, but the cost could be too high.

The Ottawa Senators have persevered through a number of injuries to key players, among them Norris Trophy-winning defenseman Erik Karlsson, top-line center Jason Spezza and goaltender Craig Anderson.

The latest addition to that list is forward Milan Michalek, who had arthroscopic surgery on his right knee Tuesday and is out indefinitely. Michalek has played just two games since originally getting hurt during pre-game warmups prior to a game against the Pittsburgh Penguins on Feb. 13.

Senators general manager Bryan Murray knows replacing Michalek with a player of similar skill won't be easy.

"I don't know how you ever get a scorer in the NHL anymore, but if you can get a top-six forward it's always the objective," Murray told the Ottawa Sun. "I haven't identified anybody who is going to be moved."

Chicago Blackhawks general manager Stan Bowman is staying busy in the run-up to the April 3 NHL trade deadline, telling the Chicago Tribune he's "had tons of conversations," but that no moves are imminent.

"I'd like to add to the mix as opposed to trade players away," Bowman told the Tribune. "We would consider anything that would give us an improved chance to win, but we've played really well. If we don't end up making a trade I'd be comfortable with the group we have here."

The Blackhawks are 2-2-0 since their record-setting 24-game streak of games with a point to open the regular season ended, but still have a five-point lead on the Anaheim Ducks for the top spot in the Western Conference.

If Bowman does make any move, he said finding a center to play on the third or fourth lines might be an option.

"Probably just be depth-type moves," he said. "We have had a nice, consistent group on defense … [and] up front, we have some different looks. Perhaps some centermen maybe as a depth thing in case you run into injuries. There's really not one area that's a glaring area [in need] of improvement."

Sergei Gonchar is a vital part of the defense for an Ottawa Senators team with hopes of getting back to the Stanley Cup Playoffs.

He's also a 38-year-old blueliner whose contract expires July 1, and according to the Ottawa Sun, Gonchar's representatives and the Senators have not had any talk about a new deal to keep him with the team.

So could the Senators look to move Gonchar prior to the April 3 NHL trade deadline?

Gonchar, who has 15 points in 25 games while playing 24:34 per game -- second on the club to Erik Karlsson, who is out for the season with an Achilles injury sustained Feb. 13 -- said he isn't concerned with any off-ice issues.

"It doesn't worry me," Gonchar told the Ottawa Sun. "I know we have to do well, I have to do well and everything [will] take care of itself. You can't go out there and think about it or worry about [it]. That won't do any good for you or your teammates. That's why I don't even think about it."

To Gonchar, all that matters is getting back to the postseason. The Senators enter Sunday 2-0-2 in their past four games, and fifth in the Eastern Conference.

"It's going to depend on the way we play," Gonchar said of his future with the Senators this season. "You have to think about it logically, and I've never had a discussion with Bryan [Murray, general manager], but what I'm thinking is if we have a chance to make playoffs, [he'll stay]. If some reason we're not, which I hope is not going to be the case, then that [a trade] is another way to look at it. My focus is the game. You can't worry about what-ifs, would-haves or could-haves. That doesn't do any good."

One of the surprise teams of the 2012-13 NHL season has been the Montreal Canadiens, who head into their game Saturday at the New Jersey Devils (7 p.m. ET, NHLN-US, CBC) leading the Eastern Conference standings.

It's a long way from last season, when the Canadiens finished 15th in the conference; entering this season they weren't predicted to finish much higher.

As the April 3 NHL trade deadline approaches, the decisions only get tougher for Canadiens first-year general manager Marc Bergevin. Does he stay with the team that's gotten the Canadiens this far? Or does he look to add pieces for a Stanley Cup Playoffs run?

"I think it's a constant revisiting of how you can improve your team on a daily basis," Canadiens assistant GM Larry Carriere told NHL.com. "That's something we started when Marc came in and it's something we do every day."
