So, it was short and sweet - although probably not so, for Glamorgan supporters.

It's a pity the group stage had to end with so many games ruined by bad weather, but eight excellent teams have made it through, four of them past winners - Kent (2007), Sussex (2009), Hampshire (2010 and 2012) and Birmingham Bears (2014).

There is plenty of life left in this season's T20 Blast and we will be back with you for the first quarter-final on 12 August.

Thank you and goodnight.

Glamorgan wicketkeeper Mark Wallace: "It's been a bit of a rollercoaster for us in the T20 this season and to go out on the last hurdle is the equivalent of a penalty shoot-out. But it would've been a lot worse to go out without playing.

"Five overs a side is such a difficult game to play. This game in itself is not the reason we've gone out of the competition, it's the 14 games as whole."

Gloucestershire wicketkeeper Geraint Jones speaking to reporter Rick O'Shea: "James Fuller bowled a fantastic over, but Graham Wagg was trying to hit him out of Cardiff, which it wasn't quite the wicket for.

"It gave us a chance to assess the surface and work out how to play it. It's massively hit or miss this five overs. It looked a good wicket where it zipped on a bit, but it probably picked up a bit of pace off the surface and for people trying to swing off their feet, it didn't quite work."

So, huge disappointment for the Glamorgan fans who had waited over three hours to see some action. But that means that the T20 Blast quarter-finals will be as follows:

Birmingham Bears v Essex

Worcestershire v Hampshire

Kent v Lancashire

Sussex v Northants

Those matches to be played between 12 and 15 August, with the winners progressing to Finals Day at Edgabston on 29 August

BBC Radio Bristol Commentator Ian Randall: "Beautiful shots from Chris Dent to finish it with two sixes. Gloucestershire win with more than an over to spare and it's a hammering. What an extraordinary evening here after we thought there was no chance of any cricket at all."

Chris Dent finished things off in style by hitting a second successive six off Michael Hogan to see Gloucestershire home with seven balls to spare. The opener finishes on 28 not out from 11 balls faced, with partner Benny Howell on 11.

Australian fast bowler Michael Hogan is one of the most consistent performers on the county circuit and Glamorgan need something truly special from him now. Dent and Howell pick up a single each from the first two deliveries, but Dent then drives through the covers for four and follows that with a huge six to bring the scores level.

Essex fans can breathe a collective sigh of relief.

BBC Radio Bristol Commentator Ian Randall: "Benny Howell went long and straight and it cleared the ropes - before being well caught in the crowd there by a man in a huge rain jacket."

It is raining heavily as 37-year-old Dean Cosker takes the ball. He made his Glamorgan debut in 1996 and now has to stifle the Gloucestershire scoring rate to revive their chances of victory. The slow left-armer is wasting no time between deliveries, but Howell hoists the fifth into the crowd where a spectator takes a good catch.

BBC Radio Bristol Commentator Ian Randall: "Gloucestershire halfway there after two of the three overs, but spin could play a part here as well as a shortage of recognised batsmen in the Gloucestershire line-up."

Benny Howell contents himself with the final ball of the over, so Gloucestershire are half-way there with three overs left.

Geraint Jones may be in the final stages of his county career, but there is nothing wrong with his eye as he clears the rope off the first ball he faces, then finds the boundary. ten off two balls, but he drags the next delivery into his stumps

A massive wicket for David Lloyd as Michael Klinger hammers the ball at Jacques Rudolph, stationed at mid-on, and departs for a single. Who's next? Ashes 2005 hero Geraint Jones.

Glamorgan all-rounder Gareth Rees: "Glamorgan have got to get this game down to the last over, even if it means Gloucestershire only need six or five runs to win. It'll create pressure then and becomes anyone's game."

Chris Dent takes a single to third man from Craig Meschede's opening ball, bringing Michael Klinger - the leading run-scorer in T20 Blast this season - onto strike. The Australian has hit 21 sixes, but is under way with one before Dent takes two with the ramp shot. The next two deliveries are dot balls, but Dent has the final word by smashing a six to take Gloucestershire into double figures.

Graham Wagg will not take the field for Glamorgan after being struck on the helmet by Craig Miles, so Andrew Salter will be pressed into service in the field as 12th man. Michael Hogan, Craig Meschede, Dean Cosker and David Lloyd are likely to be four of Glamorgan's bowlers, but who will be the fifth? It's a tough call for captain Jacques Rudolph.

Glamorgan all-rounder Gareth Rees: "Glamorgan are massively under the pump here, but that's not to say they can't go out here and win this game. If Michael Hogan opens up the bowling and finds the right lengths, who knows?"

BBC Radio Wales

Glamorgan off-spinner and 12th man for the night Andrew Salter:" I think Graham will be OK, there's no big cut or marks there. He walked off the field OK. It's always a hard one to call when you're facing five overs. You'd back Graham Wagg to hit big sixes all day."

So it's up to the Glamorgan bowlers now if they are to make it through to the quarter-finals. Graham Wagg would have probably been expected to bowl one of the five, but will he be able to do so after that blow on the head?

The Welsh county have two spinners in their XI - will taking pace off the ball be the right tactic in this situation?

BBC Radio Wales

Former Glamorgan batsman Tony Cottey: "If Glamorgan were 41-6 swinging from the hips, losing wickets, you could understand the low score. But with just one wicket down, people are going to be a bit bemused looking at it on the surface. I'd say they're 10 to 15 runs short there."
