Anderson gave a thumb's up and waved to fans in attendance at Canadian Tire Centre while leaving the ice. Robin Lehner took over in goal for the Senators.
Senators coach Paul MacLean said Anderson has a stiff neck and will be evaluated further. The goalie was seen walking into the team's dressing room, but is unlikely to play Tuesday against the Columbus Blue Jackets.
It's such a privilege to be one of these 80 great players to do this milestone, and it doesn't get better than this doing it where I started. It means a lot to me. A big thanks goes to all the players tonight who helped me to achieve that and also all the players through my career.
