Well it did seem too good to be true, for a change Ireland was almost injury free in the run up to the Six Nations. However now it looks like Horgan is to miss the first few games of the tournament which starts for Ireland on 4th February against Wales in Cardiff.
Horgan had to be carried of the pitch last night in the Leinster game against Gloucester it was a double blow for Leinster and Ireland as they lost 19-13 to the English side.
Munster will play Leicester today in what is always a crunch match between to old rivals lets just hope that the Munster men can stay injury free and manage a big win at Thomond.
