Gachkar, 28, is a former seventh-round pick of the Chargers back in 2011. He played out his four-year, $2,085,900 rookie contract with the Chargers before signing a two-year deal with the Cowboys back in March of 2015.
Gachkar finished out that contract and signed with the Jaguars as an unrestricted free agent. However, Jacksonville waived him as they trimmed their roster down to the 53-man limit.
In 2016, Gachkar appeared in all 16 games for the Cowboys and recorded 10 tackles and no sacks or interceptions.
