Trainer Robert Hickmott noticed some heat in the off-fore leg a few days later and those worst fears were confirmed on Wednesday.
“I've had a couple of occasions where they've given the leg a bit of a blunt knock with a hoof or something and the subsequent scan's been good,” Hickmott said.
“We just had to make sure it wasn't a furphy and we'd end up with egg on our face, but this morning's scan revealed it.
“It's a grade one (out of five) and only eight per cent of the tendon has a lesion so the prognosis is good for a return to racing.
“He'll have to have probably 10 months in the paddock before we start a little bit of rehab work and he probably won't be racing until late winter 2020 when into a Melbourne Cup preparation.
“We'll follow an Almandin plan.”
Hickmott trained Almandin to win the 2016 Melbourne Cup for Lloyd Williams after suffering a tendon injury the previous year.
Roadwork, treadmill and the water walker will all form part of Schabau's rehabilitation after a stint in the paddock.
