Detroit Lions cornerback Jacob Lacey has suffered a subluxation of the knee cap that will indeed be a season-ending injury for him, prompting the Lions to place the cornerback on the injured reserve list, via Paula Pasche of The Oakland Press.

Lacey was in his first season with the Lions since coming over from the Colts. At 25 years of age, the cornerback started nine of 11 games he appeared in for Detroit this season and had one interception.

With everyone taking a step up on the team's depth chart in wake of Lacey's injury, the Lions have also signed free agent cornerback Ron Bartell, via Dave Birkett of The Detroit Free Press.

Bartell, a former second-round pick out of Howard, played just six games for the Oakland Raiders this season. He provides the team with additional cornerback depth, even though there are just two games remaining on the season.
