Princess Anne is reportedly suffering memory loss as a result of the horse-related accident that landed her in the hospital over the weekend.

Princess Anne remains hospitalized as she recovers from a concussion and minor head injuries thought to have been caused by a horse while she was on a stroll at her estate in Gloucestershire, England, Sunday evening, The Telegraph reported.

The 73-year-old only sister of King Charles III has not been able to provide the exact details of the accident due to her concussion, the outlet said.

But according to the outlet, Princess Anne's memory loss "relates only to the incident" and is believed to be temporary, so it is unlikely that she will forget other details about herself, including her status as a royal.

While it is unclear what exactly happened at the time, Princess Anne's wounds were consistent with a potential impact from being headbutted or kicked by a horse, according to her medical team.

The royal -- a celebrated equestrian who has competed in the Olympics -- is expected to be discharged from the hospital later this week.

Princess Anne's husband Sir Timothy Laurence, her daughter Zara Tindall, and her son Peter Phillips were on the estate when the accident took place, according to the New York Post.

Laurence reportedly accompanied his wife to the hospital.

King Charles and other members of the royal family were informed Sunday night.

On Monday, Buckingham Palace said in a statement, obtained by Fox News Digital, that Princess Anne was expected to make a full recovery.

"The King has been kept closely informed and joins the whole royal family in sending his fondest love and well-wishes to the princess for a speedy recovery," the palace said.

Laurence also shared an update on his wife's condition after visiting her at the hospital Tuesday.

"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," Laurence was quoted as saying by People.

He continued, "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."

Laurence also told reporters, "She's fine. Slow but sure," as seen in a video shared by ITV's Chris Ship on X, formerly Twitter.

Princess Anne's royal engagements for the rest of the week were canceled in the wake of her accident.
