PARIS : Argentina international fly-half Juan-Martin Hernandez, who missed the World Cup last year and sat out seven months of action, suffered another injury setback on Friday. Hernandez, 29, came off after just 18 minutes of Racing-Metro's 22-13 win over Bordeaux in the French Top 14 after hurting an upper leg muscle. The Pumas star was forced to miss the World Cup in 2011 after suffering right knee damage.
