This rule has to be abolished. As Jim Courier said while announcing the match, the injury timeout should only be allowed to either a player who cannot literally play another point because of the injury and definitely not before his opponent's serve. Gulbis left the court up 2 sets to 1, but down 2-5 in the 4th set with Federer about to serve to close out the set. He didn't come back for 8 minutes! Federer was obviously peeved at this mysterious disappearance by Ernie. He got out of his chair and strolled the baseline waiting for Gulbis' return. What was wrong with Ernie! Did he have a sore back? Did he consult with Rafael Nadal to take one of Rafa's famed, feigned mystery time-outs? Was he able to consult with his coaches?
