"Davidson said the team was first informed of the allegations last week when the Blackhawks were in Columbus, Ohio, on Wednesday to face the Blue Jackets.
Sources told Emily Kaplan of ESPN that Perry had indeed traveled with the team to Columbus last Tuesday, a day before the game, and an incident occurred that day involving a team employee. Davidson said that Perry, who had not played in the team's 7-3 loss, was 'immediately removed' from the game once the Blackhawks were informed, and by then, the club had already opened an investigation." - ESPN
