Hale hurtled into a fence at Arden Street training on Monday, bruising his ribs and suffering a deep laceration to his shin that required stitches.
Club doctor Con Mitropoulos said the 25-year-old needed a tetanus shot and was taking antibiotics, but was otherwise fine.
"Haley hit the fence at full pelt," he said. "He's got a typical motor car accident-type bruise across his chest ... but he didn't break anything.
"A few years ago when he was a lot skinnier, if he had hit the wall he would have come off second best.
"He was lucky. He hit his shin quite hard but it was only the laceration, so we got away with that one."
Hale said he still felt a bit tender from the incident, where he led out to a wing for a mark before falling into the waist-high perimeter.
However, he trained for the entirety of Wednesday's session.
"It was one of those freak things that happen in footy," Hale said.
"When you can see your tibia through your skin it's not too good. But it's nothing a few stitches can't fix."
Mitropoulos also confirmed Ziebell, a NAB Rising Star nominee in 2009, had feared he had re-broken his leg in a training contest on the Gold Coast last Monday.
Ziebell was attempting to tackle teammate Gavin Urquhart when Urquhart's knee ploughed into his fibula.
The impact point was slightly lower than where the leg was broken against Adelaide in round 12 last year - effectively ending the 18-year-old's season.
"When I ran out to him, he said it felt exactly the same as it did when he hurt it [before]," Mitropoulos said. "He was quite convinced he had broken it.
"It's most unusual to re-break a bone that has filled with good, solid, chunky bone. I didn't think he had re-broken it [but] it was a good hit."
Ziebell was immediately sent for x-rays, but was walking around comfortably before they returned a normal result.
He resumed training last week and again moved freely at Wednesday's session.
"For a few seconds there I thought the worst but as it turns out, it's all sweet," Ziebell said.
"I thought it would be another eight weeks on the sidelines. To go through all the stuff I went through last year would have been pretty devastating."
Midfielder Leigh Adams should play in next Wednesday's intra-club scratch match in Ballarat, despite stretching his left anterior cruciate ligament during the Gold Coast training camp.
Adams was kicking with his right leg when ruckman Hamish McIntosh slid into him.
The 21-year-old, who had the same knee reconstructed in early 2008, ran laps on Wednesday and will resume full training on Monday.
"The scans showed that it had actually just given it a scare," Mitropoulos said. "It was a bit swollen.
"Had the scans showed that he actually tore fibres of that graft, then he would be doing nothing for six weeks.
"The other good thing is, given he's had a few little scares with [the knee] in major tackles over the last year or so, it's held up beautifully."
