PHILADELPHIA — By halftime, the Linc was buzzing: Michael Vick was an Eagle.

Suddenly, no one seemed to care much about the preseason game against the New England Patriots on Thursday night. All that mattered to most fans was that the disgraced quarterback had joined their team.

Agent Joel Segal confirmed the signing, shortly before the Philadelphia Eagles announced it in a text message. The team gave Vick a one-year deal with an option for a second year.

‘‘We don’t need another quarterback, especially him,’’ longtime fan Donald Crispin said.

The 29-year-old Vick, once the NFL’s highest-paid player, has been out of action since 2006. The former Atlanta Falcons star was convicted in August 2007 of conspiracy and running a dogfighting ring, and served 18 of a 23-month sentence in federal prison. He also was suspended indefinitely by the NFL.

Commissioner Roger Goodell conditionally lifted Vick’s suspension on July 27, allowing him to sign with a team, practice and play in the last two preseason games. Once the season begins, Vick can participate in all team activities except games, and Goodell said he would consider Vick for full reinstatement by Week 6 (Oct. 18-19) at the latest.

The Eagles reached the NFC championship game last season under quarterback Donovan McNabb, and are still looking for their elusive first Super Bowl win.

McNabb has led the Eagles to five NFC championship games and one Super Bowl appearance in the last eight years, and was rewarded with a $5.3 million raise in the offseason. The Eagles tore up his old contract with two years remaining, and gave him a new deal worth $24.5 million over the next two seasons.
