Walter (illness) wasn't listed on Wednesday's injury report, Rich Cimini of ESPN.com reports.
Walter was active for last week's win over the Saints but didn't take the field due to an illness. However, it appears as though he'll be available Sunday against Miami. While the 25-year-old was expected to take on a key role against New Orleans, he's unlikely to see much playing time against the Dolphins since Tevin Coleman (concussion) and Michael Carter (ankle) are both expected to return to the field this week.
