Mare's near foreleg blows up, putting her return to track and career in doubt.
Champion pacing mare Carabella's comeback could be over before it passes first base.
The winner of 17 of her 19 starts was lame yesterday, just a day after winning her first public outing in 14 months at the Rangiora trials.
But what really guts trainer Brendon Hill is that the problem leg which had kept Carabella away from the racetrack for so long is no longer the issue.
"I got her out of her box and her bad leg was perfect," said Hill.
