Price had his opponent down in the second round and looked well on his way to gaining redemption following his shock defeat back in February.
A gung-ho approach looked set to give Price the most fitting retribution at all, given that round two was the very same stanza in which he suffered his first professional loss to the 41-year-old American.
But after following up with an impressive performance in the third, it soon became apparent that Price was running out of steam and failing to keep Thompson at bay with his superior reach.
'The Tiger' connected with stiff body shots in the fourth before laying siege to the faltering Liverpudlian in the fifth, earning a standing count and a subsequent waving-off from referee Marcus McDonnell .
It is tough to see where Price goes from here, but a world title opportunity no longer looks like an option at all.
Price's promoter Frank Maloney cut a devastated figure after the fight, cutting short an interview as he was on the verge of tears.
