The Philadelphia Eagles acquired three-time Pro Bowl defensive end Robert Quinn from the Chicago Bears for a 2023 fourth-round pick on Wednesday.

The teams said the trade was pending a physical.

Quinn goes from a rebuilding franchise to a Super Bowl contender. The Eagles (6-0) are the lone undefeated team. Philadelphia, coming off a bye, hosts Pittsburgh on Sunday.

The 32-year-old Quinn is off to a slow start with just one sack and three quarterback hits after opting not participate in offseason workouts. But he broke Hall of Famer Richard Dent’s franchise record with 18 1/2 sacks last year in a resurgent season.

With Quinn, an Eagles defensive line that already has Haason Reddick, Josh Sweat, Javon Hargrave, Fletcher Cox, Brandon Graham and Jordan Davis becomes that much more daunting. He replaces defensive end Derek Barnett, who tore an ACL in the opener at Detroit.

The Eagles are holding opponents to 297.8 yards per game, which is fourth in the NFL. They’re fifth against the pass at 188 yards and rank second in interceptions with nine. When it comes to sacks, they’re tied for 10th with 17. And that’s an area where Quinn could help.

He has 102 sacks over 12 seasons with the Rams, Miami, Dallas and Chicago. Quinn was an All-Pro with St. Louis in 2013 when he had a career-high 19 sacks and made his second straight Pro Bowl the following year. He went from 11 1/2 sacks with Dallas in 2019 to just two for Chicago in 2020.

The Bears (3-4) visit the Dallas Cowboys (5-2) on Sunday. Chicago is coming off a surprising win at New England on Monday night.

Though they’ve struggled against the run, the Bears have been one of the best at defending the pass. But now, they’re without one of their most important players.
