Sources -- Chicago Bears set to trade Khalil Mack to Los Angeles Chargers

The Chicago Bears are attempting to finalize a trade that will send six-time Pro-Bowl defensive end Khalil Mack to the Los Angeles Chargers, sources told ESPN's Adam Schefter on Thursday.

The Chargers are expected to send second- and sixth-round picks in 2023 to the Bears in return for the 31-year-old Mack, a source said.

The deal marks the first major move for new Bears general manager Ryan Poles, who was hired in January.

Mack arrived in Chicago via a blockbuster trade with the Raiders in 2018. That first season, he finished with 12.5 sacks and in second place in the AP Defensive Player of the Year vote. It was the only double-digit sack season he had in Chicago; he was limited to six in 2021.
