Sidney Crosby 's concussion symptoms represent the most noted injury, but Penguins coach Dan Bylsma had updates on several others Wednesday after practice at Southpointe.
Defenseman Kris Letang , who got a concussion Nov. 26, "is feeling better and progressing," Bylsma said. Letang is not skating, and there is no indication whether he is working out.
Another concussion victim, rookie defenseman Robert Bortuzzo , stepped up the exertion level of his workout Wednesday and is expected to be on the ice today before the team's game-day skate. He has missed seven games.
Defenseman Paul Martin , who has missed four games because of an unspecified injury, seems the closest to returning, although it's not known if that will happen tonight when Philadelphia visits Consol Energy Center.
Martin and forward Richard Park (broken foot, nine games missed) resumed skating this week and, Byslma said, will join the game-day skate if they feel good after being on the ice beforehand this morning.
Forward Dustin Jeffrey , who had a setback with his surgically repaired right knee and has been out since Nov. 3, also has been skating this week. He was in full gear Wednesday for the first time.
With the his next win, Bylsma will move ahead of Michel Therrien into sole possession of second place among franchise coaches with 136.
Bylsma is 135-67-23 with a Stanley Cup title since being promoted from the Penguins' American Hockey League affiliate to replace Therrien in February 2009.
Eddie Johnston , also a former team general manager, was 232-224-60 in two stints as coach.
The Penguins have won four in a row and their past three home games. They also have some individual streaks going:
• Center Evgeni Malkin has an eight-game points streak (six goals, 12 assists) and a five-game assist streak (nine assists).
• Right winger James Neal has an eight-game points streak (seven goals, four assists).
• Left winger Chris Kunitz has a five-game points streak (three goals, five assists).
• Right winger Tyler Kennedy has a point in each of the past three games.
Perhaps the first three are no coincidence -- they make up the top line with Crosby out of the lineup.
The Flyers have made it known that Chris Pronger , their top defenseman and captain, will miss the rest of the season because of a concussion.
Losing him certainly creates a hole on their blue line, but coach Peter Laviolette said Pronger's teammates have filled the leadership void caused by his absence.
"We've had a lot of good leadership," he said. "You look at a guy like Jaromir [ Jagr ] ... certainly the [alternate captains], [ Claude ] Giroux , Kimmo [ Timonen ] and [ Daniel ] Briere . I think they've all done an excellent job.
" Max Talbot comes in with a lot of leadership and a lot of experience. Even our veteran defensemen, like [ Andrej ] Meszaros and [ Braydon ] Coburn and [Matt ] Carle . So I really don't think that's been an issue."
Kunitz missed practice because of illness. ... Jagr was one of two Flyers to break a pane of glass with a shot at practice at the Ice Castle in Castle Shannon. ... Laviolette declined to name his starting goalie, but indications are that it will be Sergei Bobrovsky rather than Ilya Bryzgalov .
