Concussion cloud now over Coles

Hurricanes hooker Dane Coles is following return-to-play protocols after showing signs of concussion, with the source mysteriously unknown.
Speaking at the side’s team announcement before the game against the Stormers, head coach Chris Boyd explained where the All Black was at.
It was said that Coles sustained a knee injury against the Highlanders and rested for two weeks while he recovered. However, when he came back to the training field he suffered a calf injury and also headaches, which Boyd admits left the Hurricanes cautious on his well-being.
“The source of that is completely unknown by us so that has made it a little bit more complex. We genuinely don’t know where he got those symptoms from but those symptoms were not apparent to us post his return to train from his knee injury,” he said.
Boyd added to Stuff regarding how he might have suffered the head injury: “No [Coles has no idea]. We’ve had a look at the Highlanders game, which was the last game he played. There’s no obvious point in time, he had no symptoms post that, so I’m not sure.
“I don’t think there’s any smoke and daggers there. I think at the end of the day he’s started to return to train and developed some headaches.”
