I didn't think it was intentional, he was probably surprised Hudson took off when he did. Even went over to Hudson as he as shooting his ft to see if he was okay. However, it's still a dirty play and could've easily resulted in a serious injury to Hudson. Should've been a flagrant 1 or at the VERY LEAST, the refs should've gone to the monitor to review it. It pisses me off when guys get flagrants when they go for the ball and wrap someone up around the shoulders. But when they undercut someone(a much more dirty and dangerous play) just because it doesn't look as vicious, nothing gets called.
