The GAA's Central Competition Control Committee have sought information regarding the incident that left Dublin footballer Davy Byrne hospitalised with severe facial injuries.
The injuries were sustained during a fracas that broke out prior to a friendly against Armagh on July 2, and as a result Byrne missed Sunday's Leinster final victory against Westmeath.
The GAA considered the matter closed as not only had Dublin not requested a probe into what happened, but the flashpoint was not included in Longford referee Fergal Kelly's match report of the challenge match.
After receiving heavy criticism for not taking action, the CCCC are to open an investigation in the aftermath of a revealing interview of Dublin manager Jim Gavin on Newstalk last Thursday evening.
Gavin confirmed that the Ballymun clubman had broken his nose and that a truce had been reached after a "frank discussion" between Byrne and the Armagh player involved.
The CCCC have viewed a video of the match, which proved inconclusive, but a top level GAA source revealed that "the matter remains open" and Gavin may be asked to reveal the identity of the Orchard County player who attacked Byrne.
