Swindon boss Paul Sturrock has signed defenders Chris Blackburn and Miguel Comminges as the Robins prepare for their League One return. Sturrock has also agreed a two-year contract with his son Blair after the striker, 25, ended last season on a short-term deal at the County Ground.
Blackburn, 24, has joined Swindon from Morecambe after rejecting a record contract offer from the Shrimps.
Right-back Comminges, 24, has signed a 12-month deal after leaving Reims.
