Financial details of the deal, confirmed by sources close to the player, were not yet available.
Despite being 37 years old and coming off an injury-shortened 2008 season, Galloway was seen by the Patriots and the Pittsburgh Steelers as still having the ability to stretch a secondary deep. Both franchises recruited Galloway on the premise that they will be Super Bowl contenders in 2009 and that he will play a key role in the offense as the No. 3 wide receiver.
Galloway, who was released by Tampa Bay earlier in free agency, looks to continue the long tradition of aging veterans signing in New England and resurrecting their careers as role players. Galloway visited with Patriots coaches and officials recently. He figures to be no better than the Patriots' No.3 wide receiver behind Randy Moss and Wes Welker.
Although he has played 14 NFL seasons, Galloway remains one of the league's fastest players and is capable of going deep.
For his career, Galloway has 682 catches for 10,710 yards and 77 touchdowns. He has caught 60 or more passes in six seasons. Last season, however, a foot injury limited Galloway to nine games and only four starts. He had 13 catches for 138 yards and failed to score a touchdown. This was his fewest receptions since 2000, when he played in only one game because of a torn anterior cruciate ligament in his left knee.
The former Ohio State star was a first-round pick by the Seattle Seahawks in 1995. He stayed with the Seahawks through the 1999 season, and then was traded to Dallas in 2000.
In addition to the Seahawks, he has played for the Dallas Cowboys (2000-03) and the Tampa Bay Buccaneers (2004-08). Galloway was one of several prominent players released by the Bucs at the outset of free agency.
Although he has never been to a Pro Bowl game, Galloway has been a four-time alternate.
