Robertson joined the League 2 side in 2017, making 18 appearances for The Robins last term, before an ankle injury picked up in pre-season has seen him out of action until now.
The 32-year-old Scot can play as a Centre Back or Right Back, having started his professional career with Sheffield United in 2005.
Following that, he enjoyed a five-year spell with Torquay United, before moves to Preston North End and Port Vale, before being a part of the Scottish League Cup winning side with Ross County in 2015/16.
Robertson returned south of the border at the end of that year after joining AFC Wimbledon prior to his current spell with the Robins.
All at the Hawks are looking forward to having Chris as part of our squad for the upcoming weeks and give him a warm welcome to Westleigh Park.
