Now, Denyer has given an update on Sailor's condition.
Taking once again to Instagram, he wrote: 'My little girl is on the mend.
'Sailor had her MRI & good news is, she checks out ok. She’s still suffering some effects of the concussion but thankfully nothing structurally wrong.
'Thanks for the messages ❤️ Who would have known cartwheels could be so hectic!!'
Grant, who shares two daughters with wife Cheryl, regularly shares sweet pictures with his fans.
The couple share three-year-old Scout and seven-year-old Sailor.
Wishing Sailor a speedy recovery!
