The 42-year-old 'Hercules' star confirmed it by posting on Instagram a picture of him pushing his mother in a wheelchair.
In the photo posted, The Rock and his mother smile widely. Ata can be seen wearing a cast on her left arm.
He wrote alongside the picture, "Taking mama home. Banged up, but she's a tough one and will make a full recovery. Grateful to see her smile. And thank you guys for all the prayers, love and well wishes."
Ata and his cousin, Lina Fanene, were hospitalised after being hit by a female drunk driver earlier this month.
