Northumberland 45 North Midlands 40
A storming comeback of 28 unanswered points in the last 30 minutes was not enough to propel North Midlands into the final at Twickenham but was sufficient to preserve their top-flight status for a second year.
Instead, it is Northumberland, their conquerors at Alnwick, who are relegated to the second-tier Shield competition on scoring difference after North Mids' fought back from trailing 45-12, keeping their margin of defeat to fewer than eight points.
Tynedale fly-half Phil Belgian's siege-gun boot put the home side into an early lead with a penalty and he went on to convert all six home tries while his opposite number, Moseley's Ollie Thomas, converted five of the visitors' six touchdowns.
North Mids were heavily indebted to their Moseley contingent, with captain and flanker Mark Evans giving them a brief lead with the first try, although his club colleagues, No 8 James Rodwell and prop Paul Coles, were sin-binned.
They were punished by tries from Blaydon left-winger Andy Fenby and right-wing Hamish Smales and fullback Will Massey, both of Tynedale.
But Moseley hooker Dean Bick made the interval score 24-12 with an unconverted try following a drive from the line-out.
In the first ten minutes of the second half, Northumberland forged ahead as Fenby scored two more tries and Darlington No 8 Will Oakes claimed one.
But it was then their turn to suffer from two men being yellow-carded.
Bick emulated Fenby's feat of a trio of tries with two more from the line-out catch-and-drive routine, then his Moseley colleague Dan Hunter made the recovery complete with his own brace of tries.
On as replacement scrum-half, Hunter found his first gap through the defence from a line-out feed, then his second after Rodwell's close-range scrum pick-up. n Warwickshire's hopes of a third consecutive group win, a Twickenham appearance in the Shield final and possible promotion dissolved after a comprehensive 35-8 defeat by Cheshire at Macclesfield.
In contention in the early stages with Kenilworth full-back Lee Cassell's penalty and a try by Nuneaton flanker Glenn Southwell, Warwickshire conceded tries to John Sewell, Tom Mapp (2) and Tim Coulbeck.
Former Ireland international full-back Simon Mason kicked 15 points for the victors.
