Tommy Berry and Glyn Schofield have confirmed they will return from Singapore to ride at the Rosehill Guineas meeting.

The jockeys flew to Singapore late last week to be with Berry's twin brother and fellow rider Nathan who was hospitalised after collapsing at Kranji trackwork.

He has been diagnosed with Norse syndrome and doctors have placed the 23-year-old in an induced coma.

Tommy Berry has a full book of nine rides at Rosehill on Saturday, all for trainer Gai Waterhouse including import Tres Blue in the Group One George Ryder Stakes.

Schofield's mounts include Boban for Chris Waller in the Ryder.

Both riders are expected to return to Singapore after the meeting.

Schofield is Nathan Berry's father-in-law and has been in Singapore to support his daughter Whitney and the Berry family.
