Vegas Golden Knights leading scorer Jack Eichel was placed on injured reserve because of a lower-body injury, the club confirmed Monday.

The designation means Eichel must miss at least seven days dating back to when he couldn't physically play.

Vegas Golden Knights defenseman Alex Pietrangelo is stepping away from the team indefinitely due to an illness in his family, the team announced Wednesday.

Pietrangelo had already missed Vegas' past four games because of "personal reasons." He has been moved to the Golden Knights' non-roster list.

The Vegas Golden Knights made former Boston coach Bruce Cassidy's return a success, as Reilly Smith scored in the fifth round of the shootout to beat the Bruins 4-3 and end their NHL record for home victories to open a season at 14 games Monday night.
