Bruins coach Bruce Cassidy said right wing Chris Wagner has returned to Boston for tests on his injured right arm and will not be available for Game 4 of the Eastern Conference finals against the Carolina Hurricanes on Thursday in Raleigh, North Carolina.
Wagner hurt his arm blocking a Justin Faulk slap shot in the third period of Tuesday's 2-1 victory that gave the Bruins a 3-0 lead in the series.
