Cauthen's connections will face a nervous wait to see if the star colt can make the field for the J & N Berkett Telegraph Hcp.
The 3-year-old holds an 85 rating and trainer Andrew Campbell's hopes of improving on that mark before the January 18 feature at Trentham have now been dashed.
"He's going well and he galloped between races at Palmerston North the other day so we put him in the open 1200 at Woodville (tomorrow) and they've scrapped the race," he said.
"He'll gallop between races again at Woodville, but there is some concern at not making the field. We'll just have to sit on him and wait."
The good news is that Cauthen will have a run in New Zealand, whether he makes the Telegraph field or not, before he heads back to Australia.
