The Lions are getting healthier as they prepare for Sunday’s game against the Cowboys.

Detroit left tackle Riley Reiff, who suffered a hamstring injury during Sunday’s loss to the Bengals, was back on the practice field today. Reiff was limited, but being on the practice field at all is a positive step for Reiff, who was out of practice on Wednesday.

Also practicing was receiver Calvin Johnson, who sat out Wednesday to rest his sore knee. Johnson, who had an outstanding game against the Bengals, seems to be fine.

Also on the practice field for the Lions were defensive tackle Andre Fluellen (concussion) and safety Louis Delmas (knee). Both missed practice on Wednesday.

The only Lion not practicing at all today is right tackle Corey Hilliard, who has a knee injury. The Lions’ decision to sign offensive tackle Barry Richardson this week suggests that they think Hilliard may miss some game time.
