Ceratosaurus has osteoderms, though. There's nothing ontologically preventing an animal from having osteoderms and feathers both, but it feels like cheating at the very least.
Yet crocodilians and birds are closer to each other than just about anything else. (besides the obvious crocodilians and other crocodilians or birds and other birds)
Especially when the crocodile is actually eating a bird.
