Ireland scrum-half suffers cruel injury blow

Luke McGrath's season could be over.

The Leinster and Ireland scrum-half limped off in the second-half of Leinster's 20-13 win over Scarlets on Saturday. Leinster head coach Leo Cullen said he was unsure about the injury at his post-match press conference, however, the Irish Times Gavin Cummiskey later reported that McGrath had suffered a knee injury but that an ACL tear had been ruled out at this stage. https://twitter.com/Cumoski/status/964922402344927232 McGrath was an unused substitute in Ireland's opening round win over France earlier this month and he scored a brilliant try in the win over the Scarlets. The 25-year-old had been enjoying the finest year of his career and his absence should create an opportunity for Connacht scrum-half Kieran Marmion to deputise behind incumbent Ireland scrum-half Conor Murray for the rest of the Six Nations. Ulster scrum-half John Cooney will now likely come into the Ireland squad as McGrath's replacement having previously trained with the Ireland team during their pre-Six Nations camp in December.
