That's a ****ed up play, another bad break for the Texans. How can the refs call that a fumble? I never saw it hit the ground on the replay, but the angle was all messed up.
It's either an interception (if it never hit the ground) or it's an incomplete pass. No way that's a fumble.
I wouldn't be upset about that one just yet. That call may come back to help the Texans retain possession. There is also zero evidence it was intercepted either. Ball will be ruled an incomplete pass.
