The 28-year-old, who joined Stevenage on a free transfer in the summer, is yet to make a single first-team appearance for the club.
It is understood that the experienced defender could make his debut in Tuesday's League One clash against Oldham Athletic, with boss Gary Smith short of centre-backs.
Iro has previously played for Columbus Crew.
