Jason Spezza played Saturday's game against Buffalo with a heavy heart.

Only hours earlier, the Senators centre learned of the "freak accident" which killed Canadian skier Nik Zoricic at a skicross World Cup event in Switzerland.

The 29-year-old Zoricic was one of his "best buddies," Spezza said Monday when talking to reporters for the first time since the tragedy.

"It's been a real tough couple of days for me," admitted Spezza.

Against the Sabres, Spezza failed to register a goal or assist, but did see 19:17 of ice time and was instrumental in the team earning a point.
