Holders MK Dons went out of the Johnstone's Paint Trophy at the second round stage as Bournemouth made a numerical advantage count at stadiummk.

Dons' French midfielder Flavien Belson received a straight red card for a challenge on Brett Pitman early in the second half, before former England international Darren Anderton snatched a winner for the League 2 outfit.

It was a disappointing night for Roberto Di Matteo's men, who proudly lifted the trophy with a Wembley win over Grimsby in March.

Despite a host of changes from the side that won so impressively at Millwall on Saturday, Di Matteo's selection still looked strong enough to see off the struggling Cherries at home.

But Jimmy Quinn's men put up a brave resistance before seizing on the opportunity presented to them by Belson's dismissal.

Di Matteo called the decision harsh after the game, and he couldn't have been in a better position with the challenge on Pitman happening right in front of the home dugout.

Sean O'Hanlon competes for possession with Blair Sturrock.

But one thing was certain - Anthony Taylor's decision to dismiss him changed the complexion of a game the Dons had been dominating to that point.

While the first half produced few outright chances, the home side were making most of the running with several players trying to earn regular spots in the side.

Florian Sturm combined well with Jemal Johnson to create some shooting space in the inside left channel but his well-struck effort stuck to the gloves of Bournemouth 'keeper Shwan Jalal.

It was the start of a good spell for the home side and when Belson bullishly broke up Bournemouth possession in midfield, his pass to the right should have been met with a better connection from Kevin Gallen.

Alan Navarro was a big influence in the Dons midfield.

While happy to commit bodies forward for set pieces, Bournemouth were more than aware of the Dons' threat on the break - a fact highlighted by Marvin Bartley's blatant clothesline on Mark Wright as the Dons winger looked to break from a Cherries corner.

It was as cynical as you're ever likely to see from the Bournemouth man and, while it was never one of the red-card variety, the offence seemed to warrant more than a yellow.

Bartley was almost on the end of the visitors best first-half opening - racing through onto Pitman's pass 10 minutes before half-time only to be blocked by Dons 'keeper Nathan Abbey, who had read the danger perfectly.

With half-time looming, Bournemouth nearly shot themselves in the foot when Jason Pearce headed Dean Lewington's cross into Sturm's pass in first-half injury time. But in lifting the ball over the racing Jalal, the Austrian found the roof of the net rather than the back of it.

Nathan Abbey denies Marvin Bartman with an excellent first-half save.

The game's major talking point came less than a minute after half-time with Belson stepping in to challenge Pitman and leaving the Bournemouth strike writhing on the ground.

Mr Taylor was in no doubt, brandishing the red card while the unaware Belson checked on his opponent's wellbeing apparently aware he may have caught Pitman.

It meant a reshuffle with the newly-introduced Luke Chadwick moving to the centre of midfield and Johnson to the right leaving Gallen up front on his own.

Predictably, Bournemouth started to enjoy better possession and as the Dons committed men forward to support Gallen, they left themselves a little exposed.

Pitman shot straight at Abbey having been played into space by Warren Cummings before directing a header wide from Bartley's cross moments later.

Anderton, busy without being hugely effective to that point, abandoned his position in front of the back four and started almost operating as a third striker. When he showed good feet to pull a cross back from the deadball line, Pitman's ambitious backheel was off target.

Kevin Gallen looks to start a Dons attack.

While filled with energy and effort, the Dons were struggling to keep the ball while outnumbered but you felt one goal would be enough if they could just produce one piece of quality in the final 20 minutes.

They produced it on 69 minutes when Alan Navarro fed Sturm on the left with beautifully-threaded pass and the Austrian stood a cross towards Gallen at the far post.

Gallen was unchallenged as he rose to meet the ball five yards from goal, but as he planted a header across Jalal, the Bournemouth 'keeper stretched out his right arm to tip the ball wide.

It was a terrific save from the former Peterborough stopper and his teammates rewarded him seven minutes later.

Having just survived a frantic goalmouth scramble from a corner and an Anderton shot from range that clipped the top of the bar, the Dons could hardly claim it was a bolt from the blue.

But when Anderton's outstretched leg diverted Danny Hollands' shot past the luckless Abbey with 13 minutes to go there was more than a touch of fortune about it.

The home side threw bodies forward to snatch a goal and force a penalty shootout late in the day - young substitute Adam Chicksen paying the price for his bravery when Scott Guyett's elbow left him nursing a gash above the eye.

But the final whistle brought their defence of the trophy to an end.
