With Florida in town to play the Ottawa Senators on Saturday afternoon, Horachek ran his first Panthers practice Friday at the University of Ottawa.
Horachek was promoted from the San Antonio Rampage of the American Hockey League by Florida general manager Dale Tallon, who fired coach Kevin Dineen and assistant coaches Gord Murphy and Craig Ramsay on Friday. The Panthers are in seventh place in the eight-team Atlantic Division with a 3-9-4 record.
"I had a heart-to-heart meeting with the team and explained to them what went on today, and the reasons for it and what my expectations were, and it was loud and clear," Tallon said. "Hopefully they get the message, because if they don't, they won't be here."
