To be fair, you’ve added commas which makes it a parenthetical phrase. But yeah - people do speak like this in real life; technically, I should have said no-one speaks like this in non-impromptu speech without sounding stilted.
“Carl said on Thursday” is definitely more idiomatic (to my BrE ears, anyway) than “Carl on Thursday said”.
