Three Ravens miss practice with illness

An illness prevented three Ravens backups (cornerback Frank Walker, safety Tom Zbikowski and linebacker Prescott Burgess) to miss practice Wednesday. The only starter who didn't practice was defensive tackle Haloti Ngata (sprained right ankle). Others who didn't practice were: long snapper Matt Katula (elbow) and safety Haruki Nakamura (chest). Tight end Todd Heap (ankle) and fullback Le'Ron McClain (shoulder) were limited.
