Former Harlequins lock Olly Kohn might have only played eight minutes for Wales, but he will be cheering them on at Twickenham tomorrow.

The Bristol-born 34-year-old made his international debut for the Celts when he came off the bench to face Ireland in the 2013 Six Nations.

He got the call by way of having a Welsh grandfather, but it proved to be his only cap as a hamstring injury robbed him of further appearances as Wales went on to win the championship.

Kohn, who lifted the Premiership title with Quins in 2012, retired from the game at the end of that same season with a shoulder injury.

Former Quins team-mates Chris Robshaw, Mike Brown and Joe Marler will start for England when Wales visit rugby HQ for the sold-out crunch Pool A clash.

“If England were playing for any other team I would be cheering for them,” said Kohn, who will be watching from the stands.

“I feel genuinely lucky to have been part of a Six Nations win, although I have taken a lot of stick from the boys for it ever since – and rightly so.

“I would like to have made a bigger contribution to that season. It was frustrating I couldn’t.

“I had been picked on the bench to play France the following week, but I pulled my hamstring in the team run though prior to our departure.

“I had already put my bags on the coach to France, so they made it there, but I didn’t.

“I never thought I’d play at that level, so I feel lucky to have had the chance.

“I’ve got one cap though – for eight minutes – and my son asks me to put it on from time to time.”

Wales have had their injury problems going into tomorrow’s game with Leigh Halfpenny ruled out prior to the start of the competition, centre Cory Allen (hamstring) on his way home and question marks over the fitness of props Samson Lee and Paul James.

But Kohn believes they will not be feeling sorry for themselves.

“I still keep in touch with one or two of the Welsh boys and they will be absolutely buzzing for this,” he added.

“They have had a couple of injuries and Leigh Halfpenny is a big miss, but they are still strong and physical.

“They will know that on their day they can beat anyone in the world.”

Since quitting the game, Kohn has found success with hog roast and sausage firm Jolly Hog, which now has permanent outlets at the Stoop, as well as stands at Test cricket grounds the Oval and Edgbaston.

Last Friday, the firm, which started out catering for private functions, launched a range of sausages for online supermarket Ocado.

“I never thought I’d get excited about watching rugby, but now the World Cup is underway I’m well up for it,” Kohn added.

“It is really weird to think that I am now probably far more comfortable talking about sausages, than I am talking about rugby.”
