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