Brown was a fourth round pick of the Giants in 2009 out of North Carolina State. A torn Achilles kept him out of his rookie season.
For his college career, Brown rushed for 2,539 yards and 22 touchdowns on 523 carries.
The Broncos are likely hoping the 6'0" 224 pound Brown can replace the recently injured LenDale White as a power back on the roster. White ironically also had his season ended by a ruptured Achilles.
