Injured NSW hooker Robbie Farah has confirmed his fitness for the next State of Origin match against Queensland while celebrating a win as a racehorse owner on Saturday.

Farah was on hand at Rosehill on Saturday with Wests Tigers' teammate Chris Lawrence to see their horse Koroibete win the 1500m race for two-year-olds.

With dark glasses covering a fractured eye socket, an injury he received in the Blues' win in the opening State of Origin game, Farah said he was looking forward to returning to the field.

"I won't be playing for the Tigers on Monday night but I'll be right for Origin," Farah said.

Lawrence, who is recovering from a hamstring injury and will also miss Monday's clash against the Broncos, and Farah are part of the Darby Racing syndicate which owns Koroibete who is named after another of the Tigers' walking wounded, winger Marika Koroibete.

The Gerald Ryan-trained gelding is the first horse Farah has raced. He ran third at his first start last month over 1200m and showed his appreciation of the extra distance when he ran home strongly to beat Amovatio by half a length.

"It's awesome," Farah said.

"This is my first city winner so it's a big thrill."

Blake Ryan, substituting for his father who was at the Ipswich meeting, said he was sure the pair could expect more wins in the future with Koroibete.

"He still hasn't got much idea. He's a dumb bugger," Ryan said.

"But he's a lovely horse improving all the time and I'm sure he has a big future."

The team for the second State of Origin match will be announced on Sunday.
