Edinburgh Rugby Ltd has officially dropped Gunners from its team name and they will revert to being known as Edinburgh.

A club statement said there were a number of reasons for the change.
"One of which is that the word Gunners is already a registered Trademark of Arsenal Football Club," it said.
Edinburgh is the name by which the team was known back in 1872, when they played Glasgow in the world's first ever inter-district match.
The capital side won 3-0 that day and will hope for a repeat when the two cities meet again in the Magners League at Murrayfield on Friday evening.
Edinburgh have a new club badge to coincide with the name change.
