100% he left on a golf cart. Shortly before this I was no more than two metres from Jesse and a member of the fitness staff who were in earnest conversation. Bit hard to hear with music nearby but Hogan was indicating discomfort and looked particularly frustrated. He got to his feet, took no further part in training, walked over to the boundary and the cart took him to the rooms for swimming. Obviously there was an ongoing in as his knee was strapped.Hoping it's only minor and somewhat precautionary. Not the best thing to see when one first arrives to training.
