The injuries Princess Anne, 73, sustained in the evening of Sunday, June 23, at her Gatcombe Park home, were a "cause for concern," a new report claimed.
"It's kind of worrying because she just can't really remember what happened," royal commentator Charlotte Griffiths told GBN's Andrew Pierce and Bev Turner. "And she was completely alone in the field."
"She was at the estate and she's known to take evening strolls to check on her horses alone," she added. "It's obviously something she does regularly, but I dread to think how long she was there on her own. I hope she wasn't there on her own unconscious - she was maybe kicked by a horse."
However, according to BBC, the Princess Royal's husband has stated that she is "fine" following a minor head injury and concussion that was allegedly brought on by a horse.
Princess Anne was visited by Vice Admiral Sir Tim Laurence at Southmead Hospital in Bristol on Tuesday for a two-hour visit.
As he left the hospital, he said: "She's doing fine, slow but sure."
When a well-wisher inquired about Princess Anne's recuperation, Sir Tim answered: "She is recovering well, thank you.
"We are both profoundly grateful to the medical team and hospital support staff for their expert care - and to the emergency services who were all so wonderful at the scene."
"We are both deeply touched by all the kind messages we have received from so many people near and far. It means a great deal."
Princess Anne is expected to fully recover, but her trip to Canada this week has been postponed, and she will not be present at the state banquet with the Japanese Emperor and Empress.
The princess was booked for a number of engagements in Scotland, Hampshire, and Gloucestershire this week in addition to the state visit from Japan.
The last surviving emperor and empress in the world, Emperor Naruhito and Empress Masako of Japan, are on a State Visit to the United Kingdom.
Following a formal welcome and a carriage ride up the Mall, King Charles III hosted a state banquet at Buckingham Palace. Unfortunately, the Japanese royal couple will not be visiting Downing Street due to the general election campaign.
The princess has received "his fondest love and well-wishes" from the King, along with "best wishes" from Labour leader Sir Keir Starmer, and Prime Minister Rishi Sunak.
Princess Anne's hospitalization is the royal family's most recent health related issue.
