CINCINNATI (AP) – The Bengals were given a one-week roster exemption Tuesday for linebacker Darryl Blackstock, who was suspended the last four games for using a nutritional supplement that contained a substance banned by the NFL.

Blackstock is allowed to participate in meetings and practices this week – the team’s bye week – without counting toward the 53-man roster. They would have to open a roster spot for him by next Monday if they want him to play against the Philadelphia Eagles on Nov. 16.

Blackstock played in the first five games, including one start, and had four tackles on defense.

The Bengals also waived cornerback Herana-Daze Jones from the injured reserve list after reaching a financial settlement. Jones went on the last Oct. 17 with a hamstring injury.
