Newcomer Chris Johnson performed well enough at nickel back last week to hang on to the job this Sunday against the New York Giants.
"I have some little technique stuff that I still have to clean up coming off of two years (of injuries), just trying to get back in the swing of things," Johnson said. "But I'd say by midseason, I should be as crisp as I was when I first came out."
Johnson was acquired from the Green Bay Packers on Sept. 3 in exchange for linebacker Robert Thomas. Despite entering the NFL in 2003, Johnson hadn't played a regular-season game until this season because of injuries.
In addition to his kickoff return duties against Tennessee, Johnson had two tackles and forced a fumble playing as a fifth defensive back.
"He's a big guy that has terrific catch-up speed," Martz said. "He really has unusual speed."
