ALLEN PARK — Rookie Nick Fairley has taken another step toward getting back to practice. The cast has been removed from his left foot and replaced with a walking boot. He watched Tuesday's practice from the sidelines on the field.

He had surgery two weeks ago. At the time the Lions said the fist-round defensive tackle would miss a significant portion of training camp.

He couldn’t be on the field with his teammates while in a cast and walking with crutches, it would be too dangerous.

Fairley said he’s taking it day by day, doing rehab and hopes to get back as soon as possible.

In other practice news on Tuesday, Calvin Johnson who didn’t practice on Sunday or Monday with a bruised shoulder was back at it.

Cornerbacks Chris Houston (groin) and Eric Wright (groin), along with DT Corey Williams (ankle) did not practice. Their injuries are not considered long-term.
