Hurricanes prop John Schwalger has been diagnosed with blood clots on his lungs and will miss the rest of the Super Rugby season.

Former All Blacks prop John Schwalger will be sidelined for the remainder of the Super Rugby season after being diagnosed with blood clots on his lungs.

Mark Hammett, who coaches Schwalger’s Wellington-based Hurricanes team, said the “scary” diagnosis was made when the two-Test All Black sought treatment for what he thought was a chest infection.

Hurricanes medical staff identified the ailment and Schwalger is likely to need blood-thinning drugs as part of his ongoing treatment.

Hammett said “I’m just pleased they got it when they did. It could have been a really scary case, particularly for a tough guy like him who would have probably just soldiered on with something like that.”

The Hurricanes sit seventh on the Super Rugby ladder and play the Queensland Reds at home on Saturday.
