Suarez seemed to gnaw at the Italian defender's shoulder during yesterday's World Cup group match in Brazil and now looks set to be banned for a lengthy period by FIFA.
It is the third time in Suarez's career that he has resorted to biting an opponent.
"It's just wrong," Murray said earlier today after reaching the third round at SW19. "I just think it looks really weird seeing a person bite someone else. I just don't see how that would come into your thinking.
"Well, obviously he's not thinking clearly at the time. There was obviously something not quite right there. I think it's the third time he's done it now.
"It's not particularly nice to see. You can understand sometimes someone lashing out or whatever. But the biting's far too much."
