"This is what happens when you try to run up steps in the dark, with your arms full, wearing flip flops. Turns out if you then try to stop your forward momentum with your face, the result is road rash," he later revealed in a statement.

"Regardless, I wasn't going to miss the Autism Speaks benefit the night after — wonderful people and I was honored to be a part of this important event," the 51-year-old actor told 'People.'

Get well soon, Brad!
