Second Test: Day Four: Bell's belter, Colly's folly and Broad's bore

IAN BELL joined Alastair Cook on the Kingsmead honours board today, the second England batsman to produce a selection-enhancing century at the second Test in Durban.

While Cook's 118 was a gritty 263-ball, nearly six-hour crusade yesterday, Bell's ton was a far more fluent affair, needed 172 balls to carve the weary South African attack apart.

He went to three figures for the ninth time in his Test career by waltzing down the track and slapping Harris back over his head for four.

But as England dominate, there is bad news too. Paul Collingwood, who added a magnificent 91 yesterday to his first Test scores of 50 and 26 not out, has just returned from a scan which revealed no fracture.

He dislocated his left index finger this morning while warming-up - the man who took a record-equalling four slip catches in the first innings of the drawn Centurion Test always puts himself through a tough pre-play session - and was taken off in some pain.

Fortunately, Bell, with help from Matt Prior (60 off 81 balls, they put on 112 together for the sixth wicket) has ensured Collingwood won't have to bat again in this Test.

Collingwood was also spotted with an ice-pack on his shoulder, suggesting the back problems that nagged him during the triumphant one-day series triumph earlier in the tour are not dealt with.

That might explain why he bowled just one over in South Africa's first innings 343, with part-timers Jonathan Trott and Kevin Pietersen called up to help the front-line bowlers ahead of the Durham man.

Already Luke Wright is being suggested as the obvious replacement for the New Year Test in Cape Town next week - but with Collingwood averaging 83.5 in this series and the best fielder out there even with one hand and a bad back, captain Andrew Strauss will be relieved there is no fracture. We await further developments.

With lunch still half-an-hour away, England moved things on to 500-6 this morning, extending their lead to beyond 150 and with high tide due at 1.40pm (it affects the pitch and the swing apparently) the afternoon might have been interesting. But Stuart Broad (x off xx balls) put down anchor and England simply lost the initiative. Quite why the Notts man decided to bat like a barnacle (the politest verdict I can conjure) nobody's sure. Bloody ridiculous is another way of looking at it. 11 runs in eight overs before lunch at 513-6. Ludicrous.

The clouds are back for day four but the gateman told me: "It won't rain, I have a direct line to God." Who am I to argue... but it's the light which could prevent a result here. The floodlights were on all day on Monday, they could be on again soon here.
