Wood replaces Anderson as England bowl, Australia swap Marsh brothers

As expected Mark Wood has replaced James Anderson for England in the fourth Ashes Test, while Australia swap Mitchell Marsh for Shaun Marsh.

There was one change to each side as England won the toss and opted to bowl in the fourth Ashes Test at Trent Bridge.

England predictably brought in Mark Wood to replace the injured James Anderson after the Durham seamer proved his fitness following ankle trouble.

Yet Australia sprung something of a surprise with their alteration on Thursday, Shaun Marsh coming in for brother Mitchell as Adam Voges, who had been expected to lose his place, earned a reprieve.

Shaun Marsh's inclusion means Australia captain Michael Clarke will bat at five. Clarke has endured a poor series to date, prompting questions over his position, but his record at five is significantly better than at four.

Voges, meanwhile, has been handed another chance to impress at a ground he is familiar with following several seasons with Nottinghamshire, with Mitchell Marsh making way after scores of nought and six at Edgbaston.

On an overcast morning, Australia's rejigged batting line-up was set to be tested after Cook - whose side can clinch the series with victory having established a 2-1 lead in Edgbaston - chose to field first.
