The actor/singer was cruising through Los Angeles when a car made a turn directly in front of him, and he was thrown from his bike when he swerved to avoid a collision.
Henderson escaped serious injury and sustained only minor scrapes on his back, and he's taken to his Twitter.com page to tell followers he is "doing just fine".
He tweeted, "Thanks for all your well wishes! Took a little spill on my bike a couple of weeks ago but I'm doing just fine now!"
Proving the smash hasn't ruined his Christmas (12) break, he added, "Enjoying spending time right now with my family opening presents, eating good food and being thankful for everything we have. Hope you guys are doing the same! Love you guys... happy holidays!"
