I just received this update about their PH. Unfortunately they didn't include his last name in their correspondence. I remember reading that he was seriously injured by a Gemsbok. Here's their update:

UPDATE on MARCO

Marco got out of Hospital on the 7th of July. He stayed in Pretoria for a week to visit the Physical Therapist and to make sure there was not complications. He came back home on 14th July and spend a couple of days home. Unfortunately he had a lot of pain in his lower back and went back to the Doctor on the 23rd of July. They found infection in his vertebra and took samples of the tissue around the vertebra where the horn went in. He was released from hospital until they have the results and correct treatment plan. On the 25th of July they admitted him back to hospital due to infection that got into his bloodstream when they took the samples from his vertebra. He was in High Care to treat the infection through his veins. They test around 12 different antibiotics that would treat the infection in the vertebra. Luckily the last one was working great and would be able to treat the infection, so he was released from hospital and could take the medicine from home. They got the infection in his blood under control but is struggling with those in his bone, so he decided to stay in the city close to the doctors. On the 10th of August he was admitted back to hospital due to severe pain in his back and they found an obstruction in his intestines so he is back in High Care in Hospital to treat the new problem. Thanks to everyone for the messages, prayers, etc. Please keep on praying for him, we hope that this will be the last time he will need to go to hospital.

Thanks for the update. Best wishes to Marco for his full recovery.

Best wishes for a 'final' speedy recovery!

Edited my post above.

I checked my DSC Frontline Foundation donation acknowledgment letter, and the injured PH's name is Marco Schoonwinkel.
