Cogliano has left the team to return home to attend to a personal matter, Sheng Peng of San Jose Hockey Now reports.
Cogliano almost certainly won't be able to link up with the team for Tuesday's matchup with the Devils due to the travel time needed to go coast to coast but could still be an option during one of the four upcoming games. Lane Pederson (lower body) figures to move into the lineup in Cogliano's stead.
