The Ottawa Senators and defenceman Chris Phillips agreed to a three-year, $9.25 million US contract extension late Sunday, according to reports from multiple sources.

Phillips has one goal and four assists in 62 games this season.

The blue-liner was in the last year of a four-year, $14-million contract and was the subject of trade speculation leading up to Monday's NHL trade deadline

Phillips feels that he left money on the table by not exploring free agency July 1, but that is of no consequence to him.

"There's no question that I gave up something," he said after practice Monday. "But what that is we'll never know because I didn't go to July 1 and test that market. It's not a concern."

The 32-year-old has spent his entire 13-year NHL career in Ottawa, spanning 925 games and 233 points (60 goals, 173 assists).

"Both on and off the ice, Chris embodies what we want from a Senators player, and we're proud that he'll remain a Senator for life," Senators general manager Bryan Murray said in a news release.

Thanks to the Phillips contract, players were upbeat in the Senators locker room on Monday despite the departure of so many teammates.

"Phillips has been around here for a long time, he's a great leader in the room and a guy that a lot of guys lean on so we're happy to see him stay," said Senators forward Jason Spezza.

"I think it's been trade deadline day for a few weeks for us now so not much has changed."

Ottawa is at the bottom of the Eastern Conference standings with 51 points.
