Green Bay Packers defensive lineman Datone Jones has been suspended one game for violating the NFL's substance-abuse policy as first reported by Albert Breer of the NFL Network via Twitter.

According to the league's substance abuse policy, Jones will be able to take part in training camp and the preseason, although he'll be suspended for the Packers Week 1 game at the Chicago Bears without pay.

With a base salary of $1.107 million in 2015, Jones stands to lose roughly $69,000.

The NFL has not published precisely why Jones was suspended. It's possible he tested positive for a banned substance or he could have missed a drug test.

Being suspended, however, indicates Jones has already entered Stage 2 of the league's substance abuse program, meaning he entered Stage 1 through a previous positive test result, self referral or for behavioral reasons, including possible arrest. Players are not suspended in Stage 1.

After two underwhelming seasons in the NFL, Jones' suspension was not a good way to start Year 3 in the NFL.

Jones' performance comes with a caveat that he's been limited by a sprained ankle in both 2013 and 2014, however.

Time is running out for Jones to live up to the expectations as a former first round draft choice, although a one-game suspension will not be his death knell.

It will, however, be imperative for Jones to be much more highly productive following his suspension. Assuming he hits no more road blocks, he'll be eligible to return in time for the Week 2 meeting against the Seattle Seahawks, the team the Packers lost to in the NFC Championship last season.
