Nashville All-Star defenseman Shea Weber has agreed to an offer sheet with the Philadelphia Flyers, the Flyers announced in a Thursday morning press release.

TSN's Darren Dreger, who first reported the story, says the deal is for 14 years and more than $100 million. Those terms were not confirmed in the club's press release.

Nashville has a week to decide whether to match the offer. If the Predators opt not to do so, it is believed they will receive a package of four first-round draft picks from the Flyers, although compensation depends on the annual average value of the contract. The Flyers' first-round pick has been no higher than No. 20 in each of the past four drafts.

Dreger reported Nashville was working on a trade and it's believed several deadlines passed before the Flyers grew tired of waiting and Weber -- a restricted free agent -- signed the offer sheet.

Weber, the runner-up for the Norris Trophy as the NHL's top defenseman, has one year remaining before he's eligible for unrestricted free agency. He turns 27 on Aug. 14 and is coming off a season in which he scored 19 goals and added 30 assists for 49 points. He was a First-Team All-Star for the second straight season and barely lost the Norris to Ottawa's Erik Karlsson.

He has played his entire NHL career with Nashville, which picked him in the second round (No. 49) in the 2003 NHL Draft.

The signing comes just two weeks after the Predators lost their other All-Star defenseman, Ryan Suter. He signed a 13-year, $98 million contract with the Minnesota Wild on July 4.
