Locke (knee) is nearing a return to the practice field, Todd Archer of ESPN.com reports.
The safety suffered a hyperextended knee during a training camp practice July 29, though he avoided a serious injury. Locke is lined up to serve as Dallas' third safety behind Malik Hooker and Jalen Thompson, and as long as he can return to the field sooner rather than later, he should have a good chance to cement that spot.
