Tootoo wasn't hurt. He was actually laughing on the bench afterwards and Doan was pointing at him yelling at the ref about it. If you think that is a remotely harmful play then honest to god you've never laced them up.
The guy that grabbed Tootoo surprised him. It was a grab, not a clothesline. Instead of getting up and defending himself, Tootoo pretends like he's injured. A penalty on the grabber for sure, but worse than a turtle on Tootoo's part.
I'm sorry, if you go in for a hit high on someone, you should be expecting someone to come explain why they don't want you to do that ever again.
