Rolando McClain may have used his last chance with the NFL.

McClain, a previous first-round draft pick, was suspended again after being in violation of the league’s substance abuse policy. In the 2016 season he will have to sit out the first 10 games.

Last season McClain violated the same policy and received a four game suspension. Once he returned, he was a starter in the final 11 games for the Dallas Cowboys and totaled 80 tackles, two sacks, and returned an interception for a touchdown.

McClain was re-signed with Dallas earlier in the year on a deal that’s incentive-laden, has a $1.25 million base salary, with a salary cap at $5 million, and included a signing bonus for $750,000. However McClain’s signing bonus may have to be repayed under the terms of his collective-bargaining agreement.

Out of Alabama, McClain was picked eighth overall in 2010. The Oakland Raiders released him at the conclusion of the 2012 season and he had been deactivated during the team’s last five games of the year. McClain also spent a month with the Baltimore Ravens and has twice retired.

DeMarcus Lawrence, the Cowboy’s defensive end, was also issued a suspension for violating the substance abuse policy. Lawrence’s appeal was denied and he will sit out for the first 4 games this season.
