New Jersey Devils forward Michael Cammalleri is week to week with an upper-body injury, according to NorthJersey.com.
"I'd say a week right now and then we'll probably re-evaluate what it would be after that," Devils coach John Hynes told the website.
Cammalleri was not at practice Friday, one day after playing 12:35 in a 1-0 loss to the Washington Capitals. He was hit awkwardly into the boards midway through third period.
Cammalleri, 34, has 10 goals and 20 assists in 55 games with the Devils this season.
New Jersey visits the Boston Bruins on Saturday (7 p.m. ET; NESN, MSG+, NHL.TV). The Devils are eight points out of a Stanley Cup Playoff position and have 19 games remaining.
