The Buffalo Sabres on Friday returned rookie Mikhail Grigorenko to the Quebec Remparts of the Quebec Major Junior Hockey League.

The 6-foot-3, 200-pound Russian, who was chosen in the first round (No. 12) of the 2012 NHL Draft, had one goal, five points and a minus-2 rating in 22 games for the Sabres.

The 18-year-old, who earned a bronze medal for Russia at the 2013 World Junior Championship in Ufa, Russia, in January, scored his first NHL goal on Jan. 29 in a 4-3 overtime loss to the Toronto Maple Leafs.

The Columbus Blue Jackets on Friday activated defenseman John Moore off injured reserve and reassigned defenseman Cody Goloubef to the team's American Hockey League affiliate in Springfield.

Moore, 22, had missed the past eight games after sustaining a shoulder injury during a morning skate at Chicago's United Center on March 1. A 2009 first-round pick (No. 21) of the Blue Jackets, Moore has two goals and eight points in 82 career NHL games. He had one assist at the time of his injury earlier this month.

Goloubef, 23, appeared in 10 games with Columbus this season and had one goal, 10 hits and six blocked shots. The 2009 second-round pick (No. 37) has posted 11 goals and 41 points in 123 career AHL games. He had five goals and 12 points in 25 matches for the Springfield Falcons this season.

The New York Islanders announced Friday that forward David Ullstrom has a groin injury that is expected to sideline him for 3-4 weeks.

Ullstrom has two goals and five points in 20 games this season. He posted four goals and eight points in 29 games during his rookie season in 2011-12.

According to Islanders coach Jack Capuano, forwards Jesse Joensuu and Colin McDonald are questionable for Saturday's game at the Florida Panthers.

The Anaheim Ducks on Friday acquired center David Steckel from the Toronto Maple Leafs in exchange for right wing Ryan Lasch and a seventh-round pick in the 2014 NHL Draft.

Steckel, 31, was a 2001 first-round draft pick (No. 30) of the Los Angeles Kings. He spent five-plus seasons with the Washington Capitals before being dealt to the New Jersey Devils in February 2011. He has spent the past two seasons with the Maple Leafs, primarily as a fourth-line center. He averaged 7:04 of ice time and had one assist in 13 games for Toronto in 2012-13. He also won 38 of 81 faceoffs (46.9 percent).

Injured Pittsburgh Penguins center Evgeni Malkin skated on his own Friday with strength coach Mike Kadar, but will not play Saturday afternoon against the New York Rangers, the team announced.

Malkin is sidelined with an upper-body injury sustained March 9 in a game against the Toronto Maple Leafs. It was his third game back in the lineup after missing time due to a concussion. The Penguins have stated Malkin's injury is not concussion related.

Malkin has five goals and 24 points in 21 games this season.

Toronto Maple Leafs forward Joffrey Lupul, who has been out since Jan. 24 with a fractured forearm, has been cleared for contact and could play Saturday against the Winnipeg Jets.

Maple Leafs coach Randy Carlyle informed the media in Toronto about Lupul's status Friday, but said he wasn't sure if he would insert him into the lineup against the Jets.

Brenden Morrow

Left Wing - DAL

GOALS: 6 | ASST: 5 | PTS: 11
SOG: 27 | +/-: -4

Morrow, who missed Tuesday's game and Wednesday's practice with a groin problem, took part in the morning skate on Thursday, and it appeared he'd be in the lineup. But Stars coach Glen Gulutzan told the media that Morrow was definitely out against Anaheim but that he and Jamie Benn, sidelined with a wrist injury, were definite possibilities for Saturday, when the Chicago Blackhawks visit Dallas.

The NHL will have a fresh look for the regular season and a new format for the Stanley Cup Playoffs beginning next season after the Board of Governors approved the realignment plan proposed last week.

The four-division plan, featuring a new set-up for the playoffs, will be in place for a minimum of three seasons, barring any franchise relocation or expansion. NHL Commissioner Gary Bettman said neither relocation nor expansion were being discussed, however.

"This goes into the good news category," Commissioner Bettman said Thursday. "We can begin the process of preparing next year's schedule."

The NHL and NHL Players' Association each had input into the plan to realign the League into a more geographically appropriate two-conference, four-division format that has 16 teams in the Eastern Conference and 14 teams in the Western Conference.

The Anschutz Entertainment Group Inc., which owns the Los Angeles Kings as well as other sports properties, no longer is being offered for sale, it was announced Thursday.

Also announced was the departure of company president Tim Leiweke, a key figure in the development of the 2012 Stanley Cup champion Kings.

"He was very adamant and very passionate about the Kings and everything that was what this organization was about," Kings captain Dustin Brown told the team's website of Leiweke. "I've been here for 10 years, and he was here in the beginning when we weren't very good, and he understands what that is like from his perspective.

The Carolina Hurricanes came to terms Thursday with defenseman Keegan Lowe on a three-year, entry-level contract.

Lowe, a third-round pick of the Hurricanes in the 2011 NHL Draft, is the son of six-time Stanley Cup champion Kevin Lowe, currently the Edmonton Oilers president of hockey operations.

At the NHL level, the deal will pay Lowe $610,000 in 2013-14, $660,000 in 2014-15 and $710,000 in 2015-16. At the AHL level, he would be paid $67,500 per season, and the deal also includes a $235,000 signing bonus. He will remain with his junior team, the Edmonton Oil Kings of the Western Hockey League, as they enter the postseason as the first seed in the WHL's Eastern Conference.
