Aug 1 (Reuters) - Fluminense's former Brazil international Marcelo was sent off in tears after his lunge at Luciano Sanchez during a Copa Libertadores match in Buenos Aires left the Argentinos Jrs defender with a horrific injury on Tuesday. Marcelo was dribbling past Sanchez when his leading foot went past the ball and caught the Argentine high on the shin with force. The Argentinos player's leg buckled underneath him at a shocking angle, leaving him lying in agony on the pitch. "Today I had a very difficult moment on the pitch," Marcelo posted on Instagram. "Fluminense FC expresses its solidarity and wishes a speedy recovery to Argentinos Juniors defender Luciano Sanchez, who was injured in an accidental move in tonight's match," it read.
