Grzelcyk (upper body) will not participate in Saturday's tilt versus Ottawa, Conor Ryan of MassLive.com reports.
Grzelcyk has averaged 18:14 of ice time -- 1:34 during the man advantage -- and been held pointless over the last five games. The 28-year-old exited Thursday's game against Carolina early after suffering an upper-body injury but returned to full practice Friday, indicating he is not expected to miss serious time. In Grzelcyk's absence Jack Ahcan will slot into the lineup, Ryan adds.
