Ross Cockrell breaks his leg during Panthers practice

The Carolina Panthers could be without a key addition off season for the defense for a while.

Cornerback Ross Cockrell who joined the Panthers for a two-year free will agreement, was removed from the field on Monday with a broken leg, by Ian Rapoport of the NFL Network Insider

Cockrell shouted: " My leg is broken ."

Panthers coach Ron Rivera ended the practice after the injury, the party said.

With Daryl Worley now with the Oakland Raiders, Cockrell had to be competing for a starting job in front of James Bradberry.

While the Panthers have Bradberry, rookie Donte Jackson, Corn Elder and Lorenzo Doss, among others, on the lineup, the depth of the team at the corner half will be tested if Cockrell lacks time . Cockrell started 32 games over his four-year career.

Here are other wounds we are watching:
