- The Giants also released LB Trevor Bates from their practice squad.
Thornton, 28, is a former third-round pick of the Packers back in 2014. However, despite his draft status, Thornton lasted just a little over a year in Green Bay before he was waived at the start of the 2015 season.
After a brief stint with the Patriots, the Lions later claimed him off of waivers during the 2015 season and he finished out the year in Detroit before returning on a two-year, $3.3 million contract this past March.
Thornton was suspended for the first six games of the 2017 season for violating the NFL policy and program for substance abuse. Detroit just recently elected to cut Thornton loose and he signed on with the Giants a few weeks ago.
In 2017, Thornton has appeared in four games for the Lions and recorded four tackles and no sacks.
