Collingwood failed twice with the bat at Old Trafford

England's Paul Collingwood is suffering from shoulder and back problems just days before the start of the home Test series against New Zealand.

He was given a pain-killing injection during Durham's 232-run County Championship defeat by Lancashire.

"Paul has received treatment for stiffness in his lower back and a sore right shoulder," said an England and Wales Cricket Board spokesman.

"He will continue to have treatment and be reassessed over the next 48 hours."

Collingwood, who had shoulder problems in Sri Lanka last winter, did not bowl in Lancashire's second innings, but Durham's director of cricket Geoff Cook sounded a positive note, saying: "I don't think there is any fear of him missing any cricket."

Collingwood, 31, has played 33 Tests and has been an ever present in the England side since the series in India two years ago.

He is likely to be included in the squad for next week's Lord's Test when it is announced by chief selector Geoff Miller on Sunday.

But his form with the bat, as well as his shoulder, will be a cause for concern after scores of three and one against Lancashire.

"Runs would be good to get that confidence going, but I'll back myself to go out there and score out in the middle when the time comes.

"I am sure that everybody has got me down as the first one off the team sheet but I am a battler," he said.

Collingwood was given a working over at Old Trafford by England team-mate Andrew Flintoff.

And if he suffers any further problems with his shoulder, it could improve Flintoff's chances of making his Test comeback following surgery on his ankle.

He has not been in form with the bat either, but against Durham, he again showed that he has lost none of his speed or hostility with the ball in his hand.

"I think that over to Collingwood was the best working-over of a world-class batsman I've seen for a long time," said Lancashire captain Stuart Law.

"Colly's a good player, but Freddie made him look almost second rate. That's just the quality of Andrew Flintoff. With the ball in his hand and the bit between his teeth, he had a point to prove.

"I don't think it would have mattered if it had been Ricky Ponting or Brian Lara - they would have felt the heat."
