Detroit and Philadelphia announced the trade on Tuesday. The Eagles gave the Lions a third-round pick in the 2019 NFL Draft in the swap for the 2014 Pro Bowl selection.
Tate, 30, had 44 catches for 517 yards and three touchdowns in seven games this season for the Lions. The nine-year veteran is in the final year of his contract. Tate had at least seven receptions in four of his seven games this season with the Lions. He had at least 90 receptions in each of the last four seasons.
The second-round pick in the 2010 NFL Draft played his first four seasons for the Seattle Seahawks, winning a Super Bowl in 2014. Tate signed a five-year deal with the Lions that offseason.
"It's been real Detroit," Tate tweeted after the trade. "I'll love ya forever. Philly Philly let's get it!"
Tate also posted a GIF from "Rocky."
Tate had 416 catches, 4,741 yards and 22 touchdowns as a member of the Lions. The Eagles have a Week 9 bye and return to action at 8:20 p.m. on Sunday, Nov. 11 against the Dallas Cowboys.
