Injury problems have plagued Robb's career and that's exactly what's happened ever since he signed for us back in June 2008. Most people expected him to be cut loose last summer, but Danny Lennon decided to give him a new deal so he could prove his fitness. However, the former Dundee United and Dundee man failed to do that and is now being let go.
The departure of Robb should free up a wage in the January transfer window and it'll be interesting to see who, if anyone, comes in to replace him.
