Munster out-half-half Ronan O'Gara suffered an ankle injury in training in Musgrave Park yesterday and medical examination later today will reveal whether or not he will be available for the quarter-final clash with Stade Francais on Saturday week. O'Gara fell to the ground after colliding with Shaun Payne and limped off the field, departing immediately to have the injury seen to. It is expected he will have a scan sometime today to determine the exact nature of the injury.

Meanwhile, Wallaby and Waratahs prop Patricio Noriega has announced his retirement from rugby union after an international career that spanned 13 years and two countries.

Noriega, 32, played 24 Tests for Australia after moving to Australia from Argentina following the 1995 Rugby World Cup, having played 25 Tests for the Pumas from his 1991 debut.
