Callum Kennedy has backed Seb Brown to bounce back after the keeper’s clanger cost AFC Wimbledon a place in the second round of the FA Cup.

The full-back was facing his own demons at the final whistle on Friday night after his own goal sealed Coventry City’s 3-1 win.

But it was Brown, a late stand-in for Ross Worner who was stuck in traffic, who took all the headlines.

The Dons had deservedly taken the lead against the in-form League One visitors in the second half through Michael Smith’s seventh goal of the season.

However, moments later, Brown dropped an innocuous cross at the feet of Callum Wilson for the equaliser.

Within three minutes, Coventry were 2-1 ahead, and when Kennedy deflected Carl Baker’s free-kick past the wrong-footed Brown with 20 minutes left, it was all over.

Kennedy, right, said: “The circumstances were hard for Seb. He has not played a game this season for the first team and he was thrown in at the last minute.

“He made a mistake, but apart from that he was very solid. I was impressed, especially with him being called upon in strange circumstances.

“He should keep his head up, he should not get too upset and he will be back.”

He added: “We played so well and carried out our game plan perfectly. We were the better team.

“Unfortunately two of their goals were fortuitous, and it’s disappointing when you score an own goal, especially when it was the killer.”

Kennedy, a summer signing from Scunthorpe United, admitted some weeks ago that he was not playing his best football at Dons after recovering from a hamstring injury at the back end of last season.

Improving: Kennedy believes his own form is getting better and better under the tutelage of Neal Ardley

However, all that has changed as the 24-year-old is discovering his true form under the guidance of boss Neal Ardley.

Kennedy said: “I thought in pre-season I was fit, but looking back, I definitely was not.

“I have noticed in the past few games that I am finding my feet again with some good performances, especially against Rochdale.

“The gaffer has said to me personally, and as a group, that training has been much better and that goes hand in hand with performances on the pitch.”

Dons return to the bread and butter of League Two action on Saturday, with the visit of Portsmouth.
