Parramatta hooker Kaysa Pritchard has been taken to hospital in an ambulance with a serious knee injury.

Pritchard was stretchered off ANZ Stadium in a medicab for the Eels after he was hurt in a tackle midway through the first half of the Eels’ NRL clash with St George Illawarra on Sunday.

The Eels dummy-half has endured a horrid run with injuries in his five-year NRL career, including twin pectoral injuries in 2015.
