It’s good to hear that Scotland will be supporting Mr O’Halloran despite his ailments. Oh no, wait. Ahaha: a laughable misunderstanding. Not “backs” as a third-person singular verb, but “backs” as an adjective, modifying “coach”. Now the sentence parses correctly: it did seem to be in want of a comma otherwise.
This is actually a bit of a hazard in rugby headlines: the number of nouns there are in the sport that can also be read as verbs. It must get tricky at times for sports subs working in tight measures. Not just “back”, but “forward” too: and “centre”, “prop”, “wing”, “maul”, “restart” … There are probably others too, but I can’t immediately think of them.
Wow, George must have really infuriated the management this time.
