The NHL is investigating an allegation regarding former Florida Panthers general manager Dale Tallon's conduct in the Toronto bubble, deputy commissioner Bill Daly confirmed to ESPN's Emily Kaplan.

Tallon is said to have used a racial slur, reports Florida Hockey Now's George Richards.

The Panthers told Richards they would not comment, and Tallon hasn't responded to Richards' attempts to contact him.

Florida and Tallon - who was the team's GM and president of hockey operations - parted ways Aug. 10, three days after the New York Islanders eliminated the Panthers in the qualifying round.

However, Tallon's departure had nothing to do with the ongoing investigation, a team source told Richards. The NHL was only recently made aware of the alleged incident, and it subsequently informed the club.

Tallon spent a decade with the Panthers after serving as the Chicago Blackhawks' GM from 2005-09.
