Looking to upgrade a secondary that has allowed 524 yards and five touchdowns through the air in two preseason games, the Detroit Lions signed former All-Pro cornerback Rashean Mathis to a one-year deal on Saturday, according to DetroitLions.com's Tim Twentyman.
The 32-year-old spent the last 10 seasons with the Jacksonville Jaguars, who drafted him in the second round out of Bethune-Cookman in 2003.
Mathis was a Pro Bowl and first-team All-Pro selection in 2006, when he made a career-high eight interceptions.
He played last season on a one-year, $5-million deal before being released in March as the Jaguars' all-time leader in interceptions with 30.
Mathis joins current starting cornerbacks Chris Houston and Ron Bartell in a secondary that allowed 26 touchdowns compared to just 11 interceptions last season. He is the third veteran defensive player the Lions have signed in the last two days following a 24-6 loss to the Browns -- they added linebacker Rocky McIntosh and defensive tackle Justin Bannan on Friday.
