The #Bills signed free agent DB Don Unamba (6-1, 192 lbs). He will wear No. 45.— Buffalo Bills (@buffalobills) July 31, 2013
Unamba (6'0", 196), a Southern Arkansas product, was a cornerback in college, but his athletic numbers (4.60 40-yard dash, 35.5-inch vertical jump) better translate to safety. He went undrafted in April and latched on with St. Louis as a tryout player in May before being released.
