"I was trying to get back for Observer, but the doctor said that was five weeks and that might be pushing it a bit, but when you have a goal, for a horse like this, it definitely helps getting up early, getting to physio twice a week and that sort of stuff."
Zahra suffered a 'v' fractured at the top of his tibia which luckily did not affect the anterior cruciate ligament of his knee.
"They said you don't break that bone without doing the ACL, so that was one good thing, I suppose," Zahra said.
"I was non-weight bearing for 10 days and after that I was straight back into it, but I was doing some rehab when I was on crutches.
"The surgeon said you will know when you've done too much, it will swell up and be sore. I pushed it to the limit most of the way, and it's absolutely fine now."
Zahra has been associated with Tentyris in five of his eight starts, including two of his three wins on the straight track at Flemington.
He said Flemington suited Tentyris' racing style once he and trainers Anthony and Sam Freedman had worked it out.
"If you get his first half of the race right and he's happy, you can see he pins his ears back and lets fly," Zahra said.
"The straight really suits him. You don't have to chase to keep in touch and when you do that, it takes his finish away.
"He's a funny horse, he doesn't want to go early, but the further he goes, he knows, and halfway through he will start to bridle up and then by the 300 (metres), if he's on song, you're skiing off him and he's ready to let rip.
"He's a beast."
