In his 16th year in the NHL and with the Senators in 2011-12, Alfredsson scored 27 goals and added 32 assists for 59 points in 75 games, while recording 18 penalty minutes and a plus-16 rating. He scored two goals in four games during the Eastern Conference quarter-final series against the New York Rangers.
"Daniel is an exceptional captain whose commitment to his teammates and to the great City of Ottawa is second to none," said Sens owner Eugene Melnyk. "Daniel expects a lot out of himself both on and off the ice so I fully understand how important a decision this was for him and his family. I couldn't be more pleased with the outcome and look forward to Daniel having a great year and adding to his long list of extraordinary achievements with our hockey club."
A six-time NHL all-star, Alfredsson won the Calder Trophy as NHL rookie of the year in 1996 and was nominated for the 2004 Lady Byng Trophy as the player demonstrating the most sportsmanship and playing ability.
"I'm excited to get ready for another season," said Alfredsson. "I’ve been training for about a month and a half and my body feels a lot further ahead of where it was last year at this point. I expect to come into camp stronger and fitter than I did last year."
