NEWARK, N.J. -- Flyers defenseman Michael Del Zotto will miss the next 7-to-10 days with an injury of the "upper-body" variety, the team announced on Sunday afternoon.

Reports from Saturday's game in Boston said Del Zotto blocked a shot off his right foot but remained in the game. This is a different injury.

With Nick Grossmann still out due to apparent concussion-like symptoms, rookie Brandon Manning will join the lineup on Sunday evening against the Devils. New Jersey will be celebrating the 20th anniversary of their 1995 Stanley Cup championship team in a pre-game ceremony at Prudential Center.

Del Zotto, 24, had been far and away the Flyers' most productive defenseman over the last two months. He's netted 7 goals and 10 assists for 17 points in his last 25 games, averaging a team-high 24:45 in minutes.

Those minutes will likely be evenly distributed between Andrew MacDonald, Mark Streit and likely Luke Schenn.

Grossmann has been out since Feb. 28 when he was hit in the back of the head while diving to block a Rick Nash shot against the Rangers. He did not skate with the team in practice this week and the Flyers have offered no further updates, other than to say it is an "upper-body" injury. He does have a history of concussions.

Devils goaltender Keith Kinkaid will make his first career start against the Flyers, opposing Steve Mason. This will be Mason's second start in a span of 27 hours, accounting for the Daylight Savings Time switch and Saturday's gut-wrenching 1 o'clock matinee in Boston on Saturday.
