Gregor Townsend takes a dig at Ronan O'Gara on Twitter

The bad blood between Scotland and Ireland spilled beyond yesterday's RBS 6 Nations clash as Gregor Townsend took a Twitter dig at Ronan O'Gara.

Scotland toppled Ireland 27-22 at Murrayfield to make good on entering the tournament with high hopes, then Glasgow boss Townsend stoked the fires with former Munster fly-half O'Gara.
