With starting safety Calvin Pryor out for the second straight game with a high ankle sprain, the Jets had only Marcus Gilchrist and Dion Bailey at the position. Miles was signed by the Jets as an undrafted free agent out of California University of Pennsylvania in 2013.
Miles was promoted to the active roster late last season, but didn't play after seriously injuring a leg in practice. He suffered compartment syndrome, which impedes blood flow, and needed emergency surgery. Miles recovered in time to lead the Jets in preseason tackles.
Harrison was the Jets' fifth-round draft pick last May out of Texas A&M.
