That is just disgusting, it's ridiculous that people here are finding excuses for his actions. Shows how low you guys are.
Did you even watch the match?? Kohlschreiber got the injury in the 5-5 in the 5th set, he didn't play injured.
The real question is did you watch the match, How could he get the injured at 5-5 in the fifth if the match didn't even go to 5-5 in the fifth, Kohli retired at 5-4 in the fifth, As far as i remember Kohli served to go 5-4 when he was injured.
