Forwards Daniel Alfredsson and Johan Franzen were back on the ice at practice for the Detroit Red Wings on Friday after both sat out an 8-2 preseason win over the Boston Bruins on Thursday with lower-body injuries.

In addition, forward Darren Helm skated for about half an hour before practice as he works his way back from groin and back injuries.

New York Islanders forward Cal Clutterbuck will miss the next four to six weeks with a leg laceration, the team announced Friday morning.

Clutterbuck was injured Tuesday in the third period of a preseason game against the Calgary Flames when he went to make a hit on Paul Byron and got cut by a skate. It was his first game in an Islanders uniform since coming to the team from the Minnesota Wild in a draft-day trade.

The New Jersey Devils reassigned 21 players on Friday, sending 15 to their American Hockey League affiliate and six others to their respective junior teams.

Goaltender Anthony Brodeur, taken in the final round of the 2013 NHL Draft, fell into the latter group, as he was sent back to Gatineau of the Quebec Major Junior Hockey League. Also returned to juniors were forwards Myles Bell (Kelowna, Western Hockey League), Graham Black (Swift Current, WHL), Remy Giftopoulos (Windsor, Ontario Hockey League), Ben Johnson (Windsor, OHL) and Ryan Kujawinski (Kingston, OHL).

New Jersey Devils forward Jaromir Jagr is expected to return to practice Friday, NJ.com reports.

Jagr skated on his own for the second day in a row Thursday, general manager Lou Lamoriello told Northjersey.com. The wing has been sidelined from training camp and preseason games since last Thursday with soreness.

The Anaheim Ducks on Thursday assigned 12 players to the Norfolk Admirals, their American Hockey League affiliate, leaving 41 players in training camp.

The Colorado Avalanche reduced their preseason roster to 42 players on Thursday by returning three players to their junior teams and sending forward Michael Schumacher to the Lake Erie Monsters, their affiliate in the American Hockey League.

The Avalanche returned forward Troy Bourke to Prince George of the Western Hockey League, defenseman Mason Geertsen to Vancouver of the WHL and goaltender Spencer Martin to Mississauga of the Ontario Hockey League.

Montreal Canadiens defenseman Davis Drewiske is expected to miss four weeks with a shoulder injury, Douglas Murray and Francis Bouillon are each day-to-day with a lower-body injury.

"These (Murray and Bouillon) are training camp injuries. It's nothing major, and we are just making sure not to aggravate those injuries," coach Michel Therrien said, according to the team's website.

"Drewiske will be out for a month. His injury is more serious, but that's why you need to have a lot of good defensemen in your system. We recalled [Darren] Dietz, who was in Kingston [when we got in touch with him]. He had to make a U-turn and come back to Montreal."

Detroit Red Wings general manager Ken Holland said veteran forward Daniel Alfredsson has a sore groin and will not play in the team's preseason game Thursday against the Boston Bruins.

Alfredsson, 40, has a minus-2 rating with one shot on goal in one preseason game.

Forward Johan Franzen also will not play. The team's website said he skated Thursday morning with the first group at Joe Louis Arena but is experiencing a painful hip flexor. Mikael Samuelsson will replace Franzen in the lineup.

Anaheim Ducks defenseman Luca Sbisa is out two weeks with a sprained ankle, the team annouced Thursday.

He sustained the injury Monday in the preseason opener against the Phoenix Coyotes. Sbisa played 18 minutes and had a team-leading five hits.

The Phoenix Coyotes on Thursday sent 10 players to their American Hockey League team, the Portland Pirates.

Among those sent down was forward Brett Hextall, who is attempting to become the fourth member of his family to play in the NHL.
