As per PFT:
"Khyri Thornton has been suspended for six games

The Lions re-signed defensive tackle Khyri Thornton ahead of restricted free agency this offseason, but he won’t be part of the lineup for the first game of the 2017 season.

The NFL announced on Tuesday that Thornton has been suspended......The suspension comes as a result of a violation of the league’s substance-abuse policy."
