- The Lions also waived Thurston Armbrister.
Ngata, 33, is a former first-round pick of the Ravens back in 2006. He spent nine years in Baltimore before he was traded to the Lions in return for a fourth- and fifth-round pick that eventually became Shaq Riddick and Za’Darius Smith.
The Lions brought Ngata back on a two-year, $12 million contract that included $6 million guaranteed. Ngata stands to make a base salary of $5.5 million for the 2017 season.
In 2017, Ngata has appeared in five games and recorded seven tackles, two sacks and a pass defense for the Lions.
Reid, 25, is a former fifth-round pick of the Lions back in 2014. He lasted just over two years in Detroit before he was waived at the start of the 2016 season and later claimed off of waivers by the Chargers.
Unfortunately, Reid suffered a season-ending ACL tear last year and was placed on injured reserve. The Chargers elected to cut him loose coming out of the preseason as they trimmed their roster down to 53 players.
The Cowboys brought him in for a workout last month but did not sign him to a contract.
In 2016, Reid appeared in seven games for the Chargers and recorded five tackles, one sack, a fumble recovery returned for a touchdown and a pass defense.
