England have received a boost with star forward Sam Burgess and playmaker Kevin Brown overcoming injury and concussion worries ahead of tomorrow's Rugby League World Cup semi-final against Tonga.

Both players ran freely at the side's captain's run today with Burgess showing no ill-effects from a slight ankle strain and Brown having passed all of his concussion tests this week after suffering a knock in last week's quarter-final win over Papua New Guinea.

Assistant coach and inaugural Warriors forward Denis Betts said both players were good to go with England's entire squad fit and firing for the sudden-death clash that's expected to be in front of a sell-out crowd of 30,000 fans at Mt Smart Stadium.

"Kevin's fit, he's always been fit," said Betts.


"He was never in doubt, we just had to run through the protocols that were put in place. He's been really good all week.

"Sam's been great. We're really fortunate that we've got a full squad training. We've got to the semi-final of a World Cup with the squad we brought over and we've still got everyone on their feet."

England's Forward Tom Burgess speaks to media after the captains run at Mt Smart in preparation for the Rugby League World Cup semi-final at Mt Smart Stadium.

The Wayne Bennett-coached side are prepared for a torrid physical forward battle against a Tongan pack led by former Kiwis international Jason Taumalolo and ex-Kangaroos star Andrew Fifita, while they also remain wary of the Pacific island side's big and skilful backline.

"There's no secret to the way they play, they run hard and tackle hard and they've got some talented people within their group," he said.

"They've got two wingers (David Fusitu'a and Daniel Tupou) that could play basketball quite easily and forwards that can trample over the top of people and have played in massive games and huge test matches for New Zealand and Australia and also in State of Origin.

"It's going to be a massive challenge for us but that's what you want - you want this place to be banging tomorrow night with the Tongan supporters."

The 48-year-old former Great Britain and England international played 42 matches over three seasons with the Warriors, after arriving in Auckland for the club's inaugural 1995 season.

Betts was pleased to back in familiar surrounds and said his family had fond memories of his time down under.

"I loved my time here and loved being in New Zealand. Not just the playing side of things but the lifestyle and personal side of things, it was something that made me better and just the times I had here.

"My eldest daughter was born here, she's got a New Zealand passport. She was 21 two weeks ago.

"I know I look young but she makes me feel old."
