Stevenage have completed the signing of free agent Andy Iro.
The Liverpool-born defender, 27, has returned to England after four years playing in the MLS.
Iro joined Columbus Crew in 2008, making 78 appearances and helping them win the MLS Supporters Shield and the MLS Cup.
Three years later he moved to Toronto, but turned down a new contract in January to return to his homeland.
The 6ft 5in centre-half could make his Boro debut at home to Bury on Saturday.
