The Carolina Panthers have jettisoned another underperforming veteran, waiving cornerback Antoine Cason on Tuesday, according to team and league sources.
Cason, who signed a one-year deal for the league minimum in March, follows the recent releases of defensive back Charles Godfrey and wide receiver Jason Avant.
Cason was one of several defensive backs signed during the offseason as general manager Dave Gettleman tried to rebuild a secondary that lost four of its top five players from last year's 12-4 team.
Cason started 11 of 12 games, but was among the lowest-rated cornerbacks in the league by Pro Football Focus, an NFL analytics site.
PFF ranked Cason 111th out of 117 cornerbacks overall, and 116th in terms of coverage.
After giving up a touchdown catch in Sunday's loss at Minnesota, Cason was benched in favor of rookie Bene' Benwikere, who will likely take over Cason's spot full-time.
Cason was 8th among corners in the latest Pro Bowl balloting that was announced last week.
