Very sad situation if Testimonials aren't being promoted out of petty feuds. Also sad if fans are agreeing with it.
Testimonial matches are supposed to be about rewarding long serving players and paying a tribute to them. Not about looking out for number 1 and pretending they aren't happening so our own pocket isn't affected. But such is the way the sport is these days, certainly at the Pro and Semi Pro level for the majority of clubs. Disappointing, but hardly surprising.
(Incidentally, I have seen Hudds promoting this via their Twitter account. It does seem like they could be doing a little more too though)
