I don't recall such an incident. As far as I know, Zhang Ning is known to be very responsible and caring coach, at the LOG she was almost six months pregnant and still insisted on accompanying the team there for coaching instead of staying home. Perhaps, it was Wang Lin's third ACL incident and the previous two cases had caused phobia in her as she herself admitted every time she played, so ZN just wanted to make sure she's not crippled by psychological fear. Of course, if WL couldn't move she would stop and that's what happened. Remember, ZN's relationship with Wang Yihan is very close, almost like mother and daughter.
