With one opening on the practice squad due to Rashad Lawrence’s elevation on Saturday, the club signed third-year linebackerSean Porter to fill out the 10-man unit.

After suffering a shoulder injury in training camp, he was placed on reserve/injured list for the remainder of his rookie season. In his second season in 2014, Porter appeared in one game before suffering a season-ending knee injury and was again placed on Cincinnati’s reserve/injured list. Porter began this season on the Bengals’ Physically Unable to Perform list and was waived on November 30. Porter played four seasons (2009-12) at Texas A&M and started 41 of 52 games and posted 261 career tackles, including 14.5 sacks and 34.5 tackles for loss.
