The breakfast TV host was taken away by paramedics on Tuesday (February 21) for treatment after falling off the horse and then getting stamped on by the animal.
Speaking from her hospital bed, Kelly noted that the incident - which occurred as she trained for a charity pentathlon - could have had a far worse outcome.
"I was given a general anaesthetic and knocked out and the wound was cleaned and stitched in the theatre," she explained to The Sun. "Luckily no skin graft was needed. The staff here have been incredible. It's the NHS at its finest.
"I did get a real shock, a real fright, but it was an accident and these things happen... I was so disappointed I couldn't take part in the challenge as the charity is such a brilliant one."
The 52-year-old added that she still faces a long road to recovery and may not make a return to Lorraine for a good while.
"I will be in hospital until Thursday night at least," she confirmed. "And then it will take a few weeks on crutches before I'm fighting fit."
