Keith Wood has been ruled out of Saturday's Heineken European Cup tie with Munster. The Harlequins hooker is suffering from a torn calf muscle and is likely to be out of action for up to a month. The injury could seriously threaten his availability for Ireland's opening Six Nations game against Wales.

Meanwhile, the Munster side to play 'Quins on Saturday at Thomond Park will be named after training this afternoon with question marks surrounding the availability of Peter Stringer, David Wallace, John Hayes and Rob Henderson.
